air compressor motor dies

Assuming it's a single phase capacitor start motor, I'd guess the starting capacitor is dead

the starting capacitor, whats that?

BTW, its a honda gas engine.

WTF! Why didn't you say that from the beginning? Leaving out a major piece of information does not help to find a solution. Starting capacitors are on electric motors, not gas engines. Most of us run compressors with electric motors.

I had a gas-powered compressor in the past. The mechanism that responds to the unloader must not be set right. The engine should slow down when the unloader is dumping air rather than putting it into the tank. When the unloader detects minimum pressure, two things should happen:

- the engine should accelerate to a higher rpm

- the unloader valve should close such that pump output goes >Hi,

Sorry bout the left out piece of info....The engien slows down correctly, at 110 psi. But once a use a small amount of air is used with an air tool, that is when it dies. Its not dying when it reaches a low psi at which the motor should accelerate. I can increase the throttle with my hand and it will still die when air is let out.
