Re: Engine suddenly shuts off
A stumbling shut off is more likely fuel related. A sudden shut off is spark related. As mentioned, fuel related issues check tank, lines, pump, carb, choke and filters. Spark, check coil connections, coil, battery to starter ,ignition switch, ignition wire to coil. Make up a 6 or 7 foot wire with alligator clips on both ends.Once it dies again, coil the wire around something round like a screw driver to create resistance, connect one end to the + battery terminal and the other to the + on the coil. Try and start and if it does, change your ignition switch. Autozone has them for under 10 bucks.
