I need help, please! Driving along and noticed the ABS light came on. I pulled into a parking lot, shut off the car, then when I tried to start the car, it went dead. Got a jump start and it started fine. When I attempted to pull out the parking lot it cuts off completely again. Then I jumped start the car again, it started, but same problem...as I pulled away from the lot, the car died. Is the alternator the culprit? Or, could it be something else?
