You may have a worn compressor clutch creating too large of a air gap which often will engage for a short time then will disengage as the pressure in the system increases from heat.
Verify that the compressor is staying engaged with the clutch, if the center part of the pulley stops spinning you have a worn clutch.
Sometimes the center part of the pulley will still be spinning, but not as fast as it should and that is also a sign of worn clutch.
To find out for sure, you will want to verify the clutch air gap. This is done with feeler gauges..
Sometimes the air gap can be restored by changing/adding/removing shims.

Found a good video on how to check the air gap, remove the clutch and how to adjust the gap..

Make sure the air gap is correct before trying other stuff..
