On the evaporator coils there should be a temperature sensor. The sensor is there to check the temperature and make sure it does not fall below 0deg C, such that ice can form. Could it be that either this sensor is faulty, or that it is detection the formation of ice? Shortly after the a/c stops working, do you perhaps see a discharge of water from the drain? -- Regards, Harry (M1BYT) (L)
