650i AC Problem

In the morning the ac works no problem, after car has been sitting in sun the fan starts to come on then goes off. Drive a little while the AC fan comes back on for a minute or so and then fan cuts back off. Changing the fan speed has no effect. When AC fan does come on it does blow cold air so it doesn't seem to be a compressor issue.

Very intermittent after car has been sitting in the sun all day. Morning no issues what so ever and can rive 3 hours with no issue.

Any help would be appreciated if anyone has ran into this issue before.

Is the temperature in the cabin remaining constant...or is the cabin over-heating (or becoming uncomfortable) when the fan stops working....and only begins to cool back down when the HVAC blower starts up again?
