I had the same issue and it was the extension cord. I was using a 100′ cord and the unit would build pressure to about 50psi and then start bogging down and shut off. I went back to my electrical training and remembered high amperage draw units are finicky when it comes to the resistance in long cable runs (100′ extension cords). I plugged it directly into the outlet and no issues since. If you must use an extension cord, use the shortest possible.
