can you get a scan tool? you can buy them for under a $100. if unplugging the fuse putting it back in works once. sounds like it resets itself. grounds have to be perfect. relays batt cable sometimes it dosent take much. my daughter had a jeep it had its quirks. engine cooling fan would stop working it was the relay. located behind the front bumper. she got rid of it. last time i worked on it was 3 yrs ago.  it would start and run few secs then die. i load tested the battery it tested ok but a new battery fixed it. plates must have broke loose in it. batt voltage should be 13.7

Start at the excitation termnal on the start solenoid with a test light or voltmeter and work back from there.  That is if the relay terminal shows power when the key is turned to start.  That will isolate the relay from the rest of the circuit.

Thid is especially important if it's a Delco style starter where the solenoid also engages the bendix.

scan tool aint goin to help you on this one
If i remember right. power goes from battery to fuse, to ignition switch, low voltage side of relay control , then ground.   fused battery through relay to starter via the one wire terminal.      What motor is in this jeep?   the 5.2 L? im guessing.
If I was you, I would have pulled the tin cap off the back of the starter on the starter, it has 3, 8 mm nuts on it.  The contacts in their get dirty and arc corroded somewhere around 140k mi on the speedo (althou my stepdads diesel was 190k) , first mark all parts with a marker or scribe, pull the 2 screws off the back of the starter body, carefully pop the back cover off  and take a look at the brushes.   these starters are so easy to rebuild its  silly.
Pop the starter out and look at those first.  Still actin up,  unfasten the pdc (power distribution center, carefully turn it on its side and pop the back cover off and look at the buss bars for water and corrosion, and carefully look at the wires next to the terminals. If you see one that is bulged or puffed up, it is corroded inside. I dont have a picture of what it looks like, but u will see it if it is. Remember you can have voltage and NO flow .

o, hey,  how is the supply wire from the bat to the starter? i know they are molded in.
is it swelled by the battery terminals?

just because it bench tests dosnt rule it is "good"  ive been down that road, take it out..bench test good.. put it back in.. NOthin .   
  where you cycle the key back and forth several times quickly  and i mean fast. then all of sudden it pops off ... solenoid.      the occasional hit and miss.. ect.       its all variable baised upon the contacts and the disc inside.   slow crank time... battery or the brushes.     I will pop one apart tomorrow and give you a picture of inside of one.

trust me here boss.. its way easy to check this first before chasin the electrical ghost.

How long have you left the battery disconnected at one time?  My hunch is it's the computer messing up.

The battery was unhooked for a couple hours at one point when we had the starter out of it. I'm sure its a weak connection somewhere or a sticky relay. It may be temperature related as well. We needed to move it today to get my truck out, and it started right up. Several times. Its in the 70's today, and was in the 90's when we were having issues.

I wanted to update this topic, because the answer to the problem was found today. It is not what I would have ever thought.

The vehicle started doing the same thing today. Dee called to find out what we had done to get it to start last time. I could not remember exactly what fuse it was I was pulling, so she called the lot where she bought the Jeep. As it turns out, the vehicle was bought at a buy here pay here lot. If your monthly payment does not clear within 3 days after the due date, they have some sort of device installed where they can disable the ignition remotely by sending out a signal. Dee had made her payments both times right on the due dates but somehow the payments did not get registered before they activated the vehicle's start disabling.  So, it turns out, I was able to over-ride their system without knowing there was a system.  I guess it is a bit embarrassing, but at least now we know. :D

I gotta think they have to tell you, but as far as I know, if they did, she forgot or paid no attention, but they did tell her today. Now she knows and I bet the payment is in early next month. :D

probably just under the pannel below the steering wheel. Most likely it will look like a remote start box.  Only other places I have seen stuff like that is a 2x2x4 box under the dash pad, REAL easy to spot as their will be wires all taped up, a bundle the size of a baseball, then feed into the magic box. the splices will be into the red and yellow wires comming from the ignition switch

I too would be removing this device!
They are a Safety hazzard!
they can give you a song and a dance all they want (the seller)  then you can tell them they are in violation of a federal law,   cant remember how it goes but its an unautherized alteration of a motor vehicle. Basically if the vehicle burns up or crashes the installers and the company that made the device are in hot water.   Who goes to say they turn the vehicle off while your going 70 down the freeway?  NO power brakes or power steering for the 100lb 5ft 4 behind the wheel?   ugh what is wrong with people that dont think.

The device doesn't have the ability to shut the vehicle off. Only to keep it from restarting once it has been activated and the car shut off. There is no big ball of tape or any such thing, as I was all over under the dash around the steering column. I don't know exactly how it works, but I know what it does. It is an interrupter in the starter solenoid circuit.

I just found this with the first search.
