My jeep has always done this ever since i got this except not in the winter. Usually in the summer with the hot temperatures and such. If i stop the jeep for like 10 minutes and go to start it back up its hot and makes a stutter and is really really rough. I have to give it alot of gas to get it to go back to normal. Now its doing it in the cold. Went wheeling yesterday shut it off for 5 minutes while i was getting unstuck and went to turn it back on twice and it died right away both times. Anyone know what this could be? ive ruled out the fuel pump. Thats about it..

 

Anyone? Fuel filter?

 

Heatsoak. Mine doesn't die, just runs real rough. Plenty of threads on it, check it out.

 

Looking for some right now

 

Don't know if jeeps have them but crank position sensor? Had them fail with these symptoms on other cars.

 

We do have CPS, but I'm definitely gonna say heat soak. Had it once when I went wheeling. It kept dieing after 10-15 seconds, and I couldn't figure out which sensor got wet. Got towed all the way back up to the trail head, and then I drove home no problem. Replaced my mechanical fan clutch (did the ZJ upgrade) and flushed the cooling system.
