IF you have lots of miles on the car in a hot climate, and the belt tensioner is holding the belt snug, then you are looking at one of two or a combination of the two issues:
Either the clutch on the compressor is worn with too much air gap and/or the compressor is worn allowing excessive thrust which causes the speed sensor not to read as it should at all times.
If the belt tensioner is in good shape and properly adjusted, then a replacement compressor is probably the best cure.

Hi,
I'm in South FL. The car has 280K. I don't know if the compressor is original or not. I know the evaporator has been replaced. Possibly the compressor. I can't figure out how to tension the belt. There is supposed to be some type of pointer, but it's not apparant to me. I tightened the new belt till it had about 1/4" deflection. Seems pretty tight to me. The new belt didn't change anything. Is there a way to bypass the speed sensor to see if that's it? I haven't timed the cycle, but it seems regular as clockwork from start to stop. That seems like it would be a good clue for anyone who understands these systems. I think if I could time it with a watch and it would be very close each time. I'd obviously like for it not to be the compressor. I certainly would hate to replace it and it not be it!
