Jeep turned off while driving
my jeep has been acting very wierd lately.. its a 99 wj with I6 4.0 with 206,xxx miles on it.. recently it started stalling out for no reason.. usually when i was standing in 1 place... today i was by my job looking for parking, and boom, jeep stalled out while i was driving.. very scary moment, because the streering wheel gets very stiff and brakes dont work as good as if the car was running.. so i stopped, and tried to start the car again, but it wouldnt start, so i desided to push it into a parking spot, while pushing it i desided to try and start the car. and it started.. i need to know what could be the problem. i stopped by my shop to ask what could be wrong and the guy told me, that it could be just a sensor(he named 2 sensors, i dont remember the names). if any1 can help me out?
