I have a 2002 Honda passport and i was getting on the highway and then all of a sudden it began to make nosies and then shutter and the engine shut off. Then i tried to start it up again and it wouldn't start. Also none of the lights turned on when I turned the key to accessory. I thought it was the alternator but the shop I brought it too said its not and its something else they just dont know yet. Anyone have an idea?
