My car has been running fine but all of a sudden the car will die when im driving down the road, sometimes it will stay off and sometimes it will start back up while the car is still rolling wqithout me turning the key. I am confused and not sure what the problem is. I was thinking maybe there is a short in the fuel regulator? I honestly have no clue what it could be. I thought once a car died it was dead until you turn it back on but since it will restart itself I dont know what it is. Any help would be very usefull. Thanks
