Thanks again for the help!

Voltage regulators do fail pretty often in these, but when they do the typical failure is that the tractor just won’t charge the battery. It should still run as long as the battery is good and providing a charge. If the piston is moving still and you think it has gas, spark would be the next thing to check.
