Probably the clutch cycling switch, when it quits cooling raise the hood and tap on the switch and it will kick in again, the switch is mounted on the aluminum accumulator. if this works get a new switch, there is a schrader valve in the port so you can change the switch easily without refrigerant loss, just screw it off quickly.
