I have a craftsman 8.5 horsepower snow thrower about three years old now. The engine will stall after about 20 min. It will start again but will not run for more than 2-3 min and stall again, this will repeat until it sits for several hours. The engine no longer has as much power as it use to either. Any suggestions how to correct these problems.

It may be getting too much gas or the choke is partially open. If it starts to run rougher after it warms up then I would suspect that its running to rich.

Check plug and see if there is fouling or dirty plug.

It starts back up many hours later because the un-burnt fuel in the cylinder dissipates enough. Then when you start it up again it takes that 20 etc to slowly flood/choke it to stall.
