Symptoms of the compressor engaging and disengaging indicates a possible fault of overfilling but if the compressor clutch relay and cooling fanes are working, then that should not be the case alone.
Test the wire to the compressor for battery voltage when the compressor fails to engage. If battery voltage is present, then the compressor clutch is bad. It could be a wek coil or the clearance between the clutches is too large.
