Looks like what i have is an older Sta-rite pump with an A.O.smith motor.
The motor keeps overheating and tripping the thermal switch about every 20 min. causing it to shut down, it starts up again after it cools down. I can find replacement motors for $160-$180, but i am considering replacing the entire unit due to its age. The problem is that there are so many choices in so many price ranges i'm not sure what are the important variables to consider when looking for a new pump. The pool was professionally installed and I "assume" the pump was sized properly for the install (in ground 18x36, 27kgal, feet of head???) I see entire pumps that are less that the cost of the new motor and others that are 10x the cost how, do you figure out what to buy?
