The causes for your issue could be too little freon or the system is overcharged or the expansion valve is bad. The average system has both a high and low compressor cut out. You will know if you are undercharged by seeing bubbles in the sight glass of the receiver dryer. You won't see them if you are overcharged, but a high side gauge will indicate too much pressure by overcharging or by the bad expansion valve.
The most common problem is loss of freon and being undercharged as a result, but John will know when he connects the gauges.
