"motor runs good wot for 5 or 10 min. then rpm's drop, still runs but slows down. if you stop and restart same thing happens. what's up???"
 
Had the same problem in the pa

Had the same problem in the past. The alarm buzzer was corroded and I could not hear it. Engine was being slowed down by high temp protection. Had to have the engine water passes cleaned to run right.
