the truck will run fine for about 20 miles or so then it sputters and dies and runs really rough. you can pop the cluch and keep it running after about 5 miles or so it runs like a top again then it will act up in about 10 miles or so it continues to do this until you stop or it dies and will not start back then if you wait about 10 min it will start up and run fine for a while.

V-6 with a distributor? Change the pickup on the distributor. Common problem.
