Answer
First, check your cooling system.  If the car is overheating, the ECM (engine control module) will turn off the a/c compressor.

Second, I'd recommend checking the amount of refrigerant in the system.  If the pressures are too low or too high, the system will shut off.  Having either too much or too little refrigerant can cause this issue.  If you don't have the equipment to recover and test the amount of refrigerant in the system, then you'd probably be best served to have a qualified a/c repair facility check the system for you.

Third, check the thermistor in the evaporator.  This is designed to shut off the compressor when the evaporator gets too cold.
