It sounds like the compressor is trying to start under load because there is a tightness in the pump itself or there is high pressure air in the line between the pump and tank There is a small valve that releases the pressure out of the main pipe that runs between the compressor and tank once the tank is full and the motor automatically cuts off. You know this valve is working by the sound of a short spurt if air being released when the motor cuts off. Releasing this pressure means that the motor is able to restart easily because there is no load. If the valve is not releasing this air, the compressor is trying to start under full load which the motor is not capable of doing, hence the slow running, overheating and popping of breakers due to a current overload as the motor tries to run up to normal peed. Motor burnout is possible if it keeps recurring.
This small release valve is attached to the Pressure control switch that switches the motor On & Off and usually has a small pipe going to it or is incorporated inside the Pressure Control Switch. If the valve appears to be working then it means that the Non-return valve on the input to the tank is not sealing properly and letting air back into the main pipe causing the compressor to start under load. Check both valves for correct operation and replace as necessary.
If all the air side checks out OK the check for low oil level and / or binding in the air pump main drive shaft.
