When it starts to blow hot, is the front of the compressor turning? Fords had a history of bad cycling switches.

I would be tempted to just replace the low pressure switch that is quick and easy. The problem must be really intermittent if an AC shop cannot diagnose? Just need to take pressure readings and keep an eye on compressor engagement.

Check the compressor clutch gap.
