So my friend has a '97 Accord. For some reason when it stops.. at a red light or drive thru for example, it just turns off and sometimes even when the car is moving and sometimes it takes multiple tries to get it to turn back on, we thought it was the alternator, so we got a new one, and it still does the same thing. We also got a new battery for it, too, just in case, and it still cuts off. What could the problem be?
