Craftsman 28": snow thrower, B&S 150000 Snow Series engine cut out

Heaviest snow storm of the season, after 10% of driveway, it cut out. Could not get it to restart by pulling. Using electric start, it would sputter for 10-20 seconds then die.

Brought it inside where it was warm, checked spark plug, all OK. No obvious water under snow hood. After sitting in warm for half an hour, it started up, and finished whole driveway, but cut out before I could start the walkway. Brought it back inside, left it overnight. In morning, it started and ran fine.

Snow was light fluffy, and wind strong. My WAG is that snow got inside something, melted and shorted some connection causing it to cut out.

If it makes any difference, the kill switch failed at the very end of last winter. I had that replaced in the fall at a reputable dealer/service center. They also replaced the 2 screws that hold down the snow hood over the spark plug, etc., and those screws might be longer than the stock ones (maybe their length makes them candidates for shorting something?)

If it tends to die when it gets good and hot then I would suspect the coil. When they start to go they can quit working when they get hot and resume working after they cool.
