I have a 60gallon kobalt aircompressor oil type. Not many hours on it. The problem is it runs fine until it gets to say 65psi , then the motor slows and lugs, at times it almost slips the belt. I let it cool down to see if it was heat related. Completely cold with 65psi in the tank, it immediately lugs when turned on. It previously pumped to about 150-155psi.
Ideas? Has proper oil level.
