I suspect the mower needs a battery connected to keep the caburetor fuel solenoid open. I theory it would continue to run if you provided 12 volts to the carb. Roger

Is the alternator regulator working is the key question. Just because it is supposed to have one doesn't mean is is working. I know for sure on the older Kohler powered JD 200 series you needed to have a battery in the sytem as an electrical storage device to keep them running. Kind of a momentary back up source of electricity to make up for the electrical charging systems power fluctuations. Roger
