EXPRESS 2500 AC Problem

My 05 Express 2500 w/4.8 litre has 150K mi. and ac works until it get above 90* outside then comp shuts off, I'm a res/light comm. ac cont. but don't know squat about automotive ac, it has plenty of refrigerant but power shuts off comp for some reason, I've swapped around micro relays & checked fuses then took it to a local shop to get "needs new shrader valve, ball valve, compressor, dryer "their spelling", orfice, o-ring, evac & recharge & labor $794.25 and seems fair but what's really shutting comp off? just trying to learn something before I have them do this and it has the same problem, TIA, rick.
