One of two issues:
1. AC unit is drawing excess current at startup. You can upsize the breaker, but the cable may then be undersized. Put a clamp meter on one of the AC feeders and cycle the unit on and off and monitor the current. Report with the current and the breaker size.
2. You may have an intermittent grounding issue on the AC unit which eventually means you will have to replace the outside unit altogether.
