It could be that the fan may not be working while the A/C is on. You may want to see if it turns on when you turn on your A/C. If the fan is working then you may want to check if the belt that leads to the ac compressor is not loose. If it is too lose then it can cause it to over heat. I suggest checking these first.
Another thing that could cause that problem would be if you haven't done a coolant flush in a while. The radiator may be dirty / clogged if it hasn't been changed and cleaned. Also when was the last time you had your thermostat replaced. An old rusty thermostat can also cause the problem.
