Thanks for the info papa. I had bought the sensor from advance. I replaced that sensor with a mopar oem sensor. The jeep ran for 90 min and died again, but this time it gave me two codes,p0340 cam sensor and p1391 manf. control ignition system or misfire. one of the possible causes listed was crankshaft posistion sensor. I replaced the crank. pos. sensor with a mopar oem. The jeep has now ran for a week. hopefully problem is fixed. dano02

yes, the Jeep has been running great ever since. I also found alot of info on this at JeepForum.com This seems to be a pretty common problem with Jeeps. There are videos on youtube showing how to replace them. Both are pretty quick and easy to change.
