I had a new compressor, condenser, and bcm put in recently and now the compressor works intermittently. It works much better when the engine is warm. The light on the dash works, the compressor just flickers on and off.

You will need to get the pressure readings of the system checked, make sure that a competent A/C tech does this as the readings are a vital part of any A/C diagnosis.

Pressures were checked by the dealership before it left last week. They had also replaced one of the hoses.

The compressor is reacting to unusual internal pressures, a faulty TX valve a part blocked receiver dryer or any other internal problem, the system pressure readings will help a good tech isolate the problem as different issues will create fairly unique pressure readings, I would go re visit the tech that repaired the system and get a new reading done.
