Here's the run down on what I've done since buying this truck at the end of Sept. Being an old Motor Head am sure this will be fixed but need some pointers if anyone has been through this before.1986 Ford F 250, 460 CI V-8, 46K miles (original), non catylitic converter, Duraspark II...

Okay so I bought this f250 about 2 months ago and was driving it around town never made any huge trips with it, but last week I was going on a 2 hour trip and 20-30 minutes in the truck just randomly dies on the highway, I had to pull to the left side and tried to crank it over, but wouldn't go...
