ECM temporarily disables AC compressor during acceleration for more power so it ceasing when giving gas is normal.
I suggest you clean off and look into sight glass of the receiver/dryer to make sure you don't have contamination in system. A few other thoughts: Overcharge, too much oil, or bad Expansion Valve. Too much oil or incorrect pressures due to overcharge or bad EV would bog down compressor. It's common DIY mistake to use refrigerant with added oil when it's not needed. No oil needed unless parts in system are replaced.
