I see questions like yours here on the board all the time and even though I am completely qualified to trace down the problems it’s basically impossible to do that Without actually having the truck in front of me. I could listen dozens of things that could cause your issue. Find a good shop in your area that specializes in older vehicles has a good reputation and take it there for a diagnosis. A sharp mechanic with plenty of experience on old stuff will have this figured out with an hour of shop time no sweat.......
