At times it will not start. It will turn over fine, but will not start. Can go out 1 hour or so later and will start just fine. On the way to town it quit completely and would turn over fine, but not start. Towed to dealer. Next day started fine. Was there a week and started each day. Took it home. Has been starting every day. Have replaces plugs, wires, coils last year. Electrical problem?
