The most common cause for your problem is poor air flow across the condensor due to bad fan clutch. And sometimes the compressor may shut off if idle speed is to low. Open hood see if clutch on comp is turning if so check fan clutch with engine at op temp fan should be hard to turn by hand also see if fan wobbles when you move the blades back and forth ie. Engine off during fan check.
Let me know what you find
