Driving with A/C on, it is cooling. If I hit a bump it it continues to run but air is warm, hit another rough spot it comes back cool again. It makes a sound when this occurs like compressor is coming on and off. I may drive several miles between intervals.

I would start by checking the connector at the A/C compressor. The jolt from the bump may be causing the connection to be not good.I attached the location of the connector at the compressor.

I also attached the wiring diagram for you to view. That connector is common for coming loose.
