Well, after looking at several other threads It doesn't appear Uncommon for the Grand Cherokee's to shut down without warning. My problem happened yesterday when the Jeep shut off in a drive thru. Would not restart. Would only turn over. Gauges not registering when key is turned. While towing it home....gauges started to register again. Ran for a few min. in driveway then cut out again. Figuring it could be PCM or wire shorting somewhere. Pcm does feel quite hot to the touch. Any advice would be appreciated. Dont have $$ to throw at it right now.

P.s. Also, did find a spot in Large wire harness where wire insulation has been worn thru on valve cover bolt. Could this have fried Pcm?
