I have been having trouble with this jeep for some time now. It will usually crank and run fine for 30-45 minutes and then without warning it shuts off, doesnt sputter or act like it is starving for fuel it just shuts off. Also if you drive it for 30 minutes or so and turn it off it will not crank again for about an hour or two. This leads me to believe it is an ignition problem and that something is getting mixed up after the engine gets hot. I think it is ignition since when it does die it is very sudden, not with spitting or sputtering like it is out of fuel, so I immagine it is probably not getting any fire for some reason. This is a 4.0 liter engine. Any suggestions?
Might check the crank sensor. it is located on the transmission bellhousing on top just off to the drivers side. if the pcm loses this signal the vehicle will die immediately and not restart until it sees the signal again
