Check your charging system, and current flow to the compressor clutch at idle.
if you have issues with your charging system, and current gets too low at idle, there may not be enough current to hold the clutch engaged.
Rather than becoming completely disconnected, it could be slipping, which will burn up the clutch very quickly.
