Hey all I'm new to the forum. I just picked up a 2001 TJ Sport 4.0 with MT and about 100k. Looks like I'm the first one to ever take it off road as it's all stock and super clean. I took it to a few local jeep spots yeaterday and was messing around on a couple hill climbs and as I went up steep inclines the my rig would shut off and I'd slide back down the muddy rock filled hills with no power brakes. Does my jeep have a rollover or engine cutoff switch? Any other reasons why this would happen? Any help would be appreciated. Thanks.
