mercedes chasis 202 ac system working perfectly for 2 hours and suddenly cuts of on 2000 Mercedes-Benz S430

i use my aircondition and it works for two hours and suddenly it just cuts off the cold air, instead it will be just blowing normally, i checked the radiator fan it was not funstioning properly so i got it changed, thinking it was not working and thus radiator getting hot and condensor also getting hot, thus the ac cut off.but the problem is still there do you think it could be the thermostat? which is hiking the temperture?
