94 850 Turbo A/C, 110,000 miles 850 1994

I have a similar problem in a 1996 850 turbo with 78,000 miles. The real problem in my case is overheating. The "brain" in this car is smart enough to turn off the A/C when the cooling system goes too far above the normal operating range. The A/C comes back on when the engine cools off a little.

Watch your temperature gauge and see if it goes above halfway just before the A/C cuts out. Mine cuts off at about 2/3 up the operating range, and that happens when the outside temperature goes above 88 degrees in heavy traffic. It can also happen in normal driving when the outside temperature reaches 96 degrees or more.

Another post on this site says the source of this problem is trash, bugs etc. in the radiator. That seems likely since I have had the water pump and cooling system checked over with no problems found. The system is not losing coolant.
