I have a 99 jeep cherokee sport 4x4. 133000 km. it randomly shuts down while driving, or idling.no check engine light comes on. 90 % of the time it stalls, it fires right back up with no struggle. I changed the plugs even got a whole new distributer. I have good fuel pressure. not sure if its my computer or a censor or something else. PLEASE HELP!!!! somtimes it runs fine for days but somtimes i cant get it out of my driveway.

 

mine did that. it was the o2 sensor. i cant remember which one. replaced both of them tho. try that.
