You probably have the same.

In my troubleshooting, I changed the tensioner as well as the belt with no success.

I was observing the compressor cycle at idle, it was cycling fine. At about the tenth cycle, I noticed the clutch would start slipping and then stop (not engage, and A/C stops working) AHA !!

I think the clutch material is either wearing out, or the gap should be adjusted (in my case). I have not done it, but now I know why the A/C stops, sporadic clutch slippage.

You may want to check that.
