Evacuate some of the freon. When it gets hot outside (and inside the engine compartment), the pressure increases internally and in your case (because you're at the threshold of being overfilled), causing the high pressure A/C sensor to kick the compressor off intermittently.

Let it down to about 30-35 PSI and report back. You can do this by sticking a thin screw driver into the low-pressure side cap and pushing down the valve inside. Be careful that your face is away from the direct upstream path of that valve. I realize this is technically illegal, but he's draining just a few PSI and will save him money and time of getting the entire system diagnosed and "repaired".
