well...is it overheating? if it just gets up to normal temp or around there and then turns off...it's not the thermostat. does the jeep turn off like you turned the key off? or does it start to sputter and die?

There are a host of things that can cause this. Runs from a failing ignition coil to failing fuel pump, to a cam / crank sensor to ????
A good place to start is to retrieve the Diagnostic Trouble Codes (DTCs).
Simple procedure - - - with a pad and pen in hand, sit in the driver's seat, and don't space off. You must pay attention, so don't be distracted.
Turn the key ON (don't start it), then OFF, then ON, then OFF, then ON, and wait, don't turn it off yet.
Watch the "Check Engine" light. It will begin to flash codes to you. They will be flashes, a pause then more flashes, then a longer pause and more of the same.
The first flash sequence is the "10s" and the flashes after the short pause are the "1s".
So --- *** pause **** longer pause equals a "34" and a **** pause ** longer pause equals a "42" When all of the codes have been displayed, there will be a ***** pause ***** - code "55" which indicates that there are no more to come.
Then refer to a repair manual available at the local parts store or on-line or at the book store. If money is an issue, go to the library in the REFERENCE section.
Follow the proper DIAGNOSTICS to locate the fault or failure, and follow the trouble tree for testing. THEN make repairs. This way you won't assume there is a failed component when in fact it might be a connector, or a related system and not the component at all.
If you get distracted, just turn the key off > 20 seconds and start again.
Do not disconnect the battery or the codes will be erased, and you won't have this useful tool until it fails again.
Good Luck and Merry Christmas
