What is wrong with my Craftsman air compressor 921.152100?

Did not build pressure. Replaced cracked regulator, then replaced starting capacitor. Now, builds to 50#, stops, surges and quits. Keeps surging and quitting over ande over. New capacitor has 2 wires. Could it be hooked up wrong? Local repairman says makes no duifference. (Original problem was stopped up air intake by mud dauber which I fixed.)
