AC York Compressor Clutch Acting Up!!!

Those can both be measured - monitor the voltage to the clutch (as close 
to clutch as possible) during operation/"failure", and check the ground 
continuity with a load (like a turn signal bulb), not just a meter.

Under what conditions (besides "cold enough") does the system turn off 
the compressor on your car?  Check to make sure everything in that path 
is working properly.

You may simply need to fix/replace that clutch, of course.  Or the whole 
compressor assembly...
