I have had my alternator and battery replaced within the last month and my car is cutting off while I'm driving it. The lights on the dashboard come on the radio powers off and the wheel starts jerking back and forth and it cuts off or begins to cut off and corrects itself. I was driving in the city during these incidents and the car was either turning or pulling off. Once on the highway it cut off while in motion.
