A/C Clutch clicking issue

[Millar.C87]

Im sure there is a thread on this but i feel its easier to post my problem rather then search all the A/C issue threads. Alright the problem I have is, A/C works great no issues nice and ice cold for about the first 30 minutes. Seems like once the clutch or compressor gets hot it starts to act up. What it does after the 30 mins the clutch tries to engage and it will not. It just keeps trying over and over about 5 times clicking really hard and loud, and never engaging again after that. It will just do it over and over like its normal cycle, causing the air to get hot. I usually turn the A/C off for a little bit and then turn it back on. But now it will only run good for about 5 mins and then start the hard clicking again. This is a unusual problem I haven't seen before. I had one person tell me it sounds like its dropping voltage to the clutch. So i put a meter on it and it stays at 13.2volts when it is engaged. When it does the hard clicking(trying to engage) the voltage just bounces around. I would assume to the fact that the clutch is not engaging properly. So I tried to send power straight from the battery with a jumper wire just to see if it is a harness issue dropping voltage, once I jumped it, it instantly stalled the car out. I Think its a bad clutch but I don't clam to be a A/C expert. So figured I would try to get some advice and maybe I miss troubleshoot something or didn't troubleshoot something I should. Thanks for any advice and sorry for the long write up. Figured Id share all the info I have on the problem and what I've tried so far.

When you were jumping the power was the a./c switched on? if not the extra load the car isnt adjusting for could be causing the stall. The next thing I would do is put some gauges on it and see what the pressures are doing once the problem starts.

I jumped it while the AC was switched on. I did it in the middle of it trying to engage over and over. I haven't put a set of gauges on it yet. I put a single gauge on the low side and it would read around 40 when the clutch is engaged and would rise to around 60-70 when it's not engage. Which is part of it cycling on and off I would assume. When the clutch acts up the gauge just bounces around the 50-60 I assume because its trying to engage but it's not. If I need to put a set of high and low gauges what would I need to be looking for that could be causing this issue?
