Sounds like the air gap between pulley and a/c clutch is too much now due to wear. when it quits open hood and take a piece of wood or something and push on a/c clutch if it engages and starts back working this is problem. be careful when doing this

you can adjust air gap by removing nut and sliding off clutch there will be a couple washers in there take one out . be sure it will still free wheel when a/c is not on.

yes it sounds like the pressure regulator. the only way to be sure is have a scan machine put on the truck, then you can see the pressure when truck is cold.They are quite pricey so dont just change it without checking the pressure first.
