I have a craftsman 16.5 Starts up good. Start cutting and about 15 20 Minutes cuts out and dies. Starts up at half throttle and starts to die out again.
I think it might be the gas solenoid????
Help

A usual clue to an increased run time failure is increased component temperature. The ignition coil is many times suspect.
