I've seen this a few times before, most often multiple small air leaks or one major one, if you find no air leaks (under covers and at pneumatic components) it would be wise to prove that the compressor is failing. Good Luck, Steve

There should be a pressure release down by where the grease zerks are. Try releasing the pressure manually. Could be you have water trapped in the system.
