Help! Jeep just shuts off when driving.

Yesterday, I was in the turn lane on a busy street. I go to turn and all of the sudden my jeep dies. Luckily, I coasted to the side of the street I was turning on. Then again today, I was going in a parking lot and went down in this little ditch between it and a backstreet and it died again... (Although, I did almost coast to the parking spot)...

Not sure what is wrong, it has never died on me when driving. Any ideas?

Thanks,
Zach

Does it just die, or is it sputtering/stalling and then dying? If it is just dying I would suspect an electrical problem, ie; a short in a wire somewhere possibly in the ignition system.

I had a vehicle that would do that years ago, and it drove me nut's looking for the problem, I finally found a small nick on the insulation of one of the wires going to the coil, that was grounding out on the firewall. I guess if I hit a bump just right, the wire would flex, ground out and the car would die.

I did have a stalling issue with my Jeep recently that may help, it would stall/sputter/loose power when making left turns. It wouldn't do it all the time, and was difficult to reproduce at will. It ended up being the fuel pump.

If you get a chance post more about the symptoms, and what year/engine your Jeep is (this may help others diagnose your problem). In the meantime hope this helps

I'd feel safer hunting with Cheney than, going for a drive with Ted Kennedy.

I am having the same problem with my 89 yj. It runs great but shuts off while driving or just idling. After it shuts off i usually have to wait about 5 to 10 minutes and it starts right up again. It doesn't matter if i am on level ground on an incline or decline or turning it just shuts of. I thought I might have gotten some bad gas so I filled up and added some fuel treatment but that hasn't worked either. If you find out what the problem is drop me a line.

I had the same problems on my 88 and 93 cherokees. It is a crank case sensor cable located behind engine along firewall down towards tranny. It usually dies or gets heated along engine causing a short. When installing, be sure to secure it against firewall so it wont touch hot engine.

Its more than likely the crank sensor cable. My 88 and 93 had the same problem. It is located behind the engine down towards the tranny. It either went bad or it is touching the hot engine causing it to ground out. Either way, replace it but its not cheap. The sensor costs over a hundred bucks.
