Sounds like the thermal protector for the motor is tripping. This means there is a problem with the motor overheating.
It is a self resetting switch so when it cools off enough the pump will come back on. It also means you probably need a new pump.

Why would my pool heater stop working after 3-5 minutes?
It likely is having a problem in the header. There are two items called High Limit switches in there, that open when a preset water temperature is reached. These can go bad, or they could be opening because they are doing their job. Based on your description, they are doing their job. I would start to look for a problem with the heat exchanger and with the internal bypass assembly as my starting points. These can cause an overheating situation.
