bad coil, or more likely, gas is very slowly feeding the carb. Pinched line, gas tank not vented, or clogged fuel filter.

Does it have an Anti Backfire Solenoid? My tractor was doing something similar because of the ABS.

HAHA. Take gas cap off and run it, then see how long it will run. That would do it. Smile

Yep, gas tanks need to be vented. I've had a couple get plugged.
