Sounds like some blockage on the high side. What's the high side pressure right before the engine stalls?

If you read through the posts you will learn he states he doesn't have a high pressure port.

I stopped following this thread after my first post and said my peace and that fell deaf ears. I only started to follow this thread again after the OP posted the video and reiterated that the belt was slipping. So I didn't read that part.
Anyway that's the OS's first problem. Not having a high or low port in a A/C system is like car without a gas cap. It's a standard item.
MacTrader, if you're reading this check your A/C mounting again. I saw that compressor shift a little when it kicked in.

That is all good to find out.
If they let you return that thing then consider getting your money back and buying a modern sanden......

Seems pretty clear now what I have to do to fix this.

Thanks Everyone
