hey guys please help me solve a problem, that even the stealership couldnt solve. check it out; i have a 95 xj ho,5.5 lift & lockers. heres my problem, sometimes when i hit a bump just right, my jeep will just shut off.so i pull over out of the way. it will happen on freeways, and when im wheeling.here is the kicker, it will crank, but not start. but when i disconnect&reconnect the CPS it fires right up no problems. i have already replaced the computer, the cps 5 times, the distributor,coil and all relays.plus the alternator. i have 271,000 miles on her. is my XJ just wore out, or do i have some sort of bad juju. may i please recieve some holy jeep advice. thanks guys.
