Again, thanks for the tips and comments. This morning, I disconnected the battery and cleaned the posts and cable ends. I also removed the ground strap from the frame and cleaned that and applied some silicone grease to the connection. Again, the truck started promptly so I drove it to my mechanic Freds shop who proceeded to trouble shoot it. He found the problem after about 20 minutes of poking around and looking at my service manual. The dumb owner of the truck had the generator rebuilt but did not connect the wires to the proper terminals on the generator. Fred switched them around and all was good. He gets another bottle of Bulleit Rye Whiskey.
