Hello I have a single speed 1.5 hp Pentair pump (Model No. Sf-n1-2a/340039) for the jets in my spa which is located inside my pool. The pump has worked well for years. Now it runs for about 10 minutes or so and then shuts off. After a while, it starts again. It seems like it’s overheating or something like that. Is this something repairable or should I get a new pump? I have checked all around the pump to make sure that it has good ventilation. Thank you

Make sure all of the electrical connections are clean and tight -- with the power off, of course!! 
Loose connections can cause overheating.

Usually when any electric motor with a thermal protection switch, which I am only assuming it has, turns off and restarts, it is either actually getting too hot or the thermal sensor is failing.
Heat can be a result of the motor itself (failing capacitor, windings, etc) or the electrical supply is starving it.
In short, there’s a lot of things that could cause it.
