2000 isuzu rodeo- v6 wont start w/o jump, cuts off while driving
My car wont start without a jump. Once I jump the car off it will run anywhere from 5 seconds to 15 minutes and then cut off and it has no power. The horn, lights or anything wont work. I've had the battery and alternator tested and they are both fine. What else could be wrong with it? I really don't want to spend a butt load of money. Someone said it could be a sensor but which sensor would cause the car to act this way?
