i remember that year truck use to have what is called a vapor lock which means the gas is dissipating before it reaches the carb so some where near your gas lines there is a heat source causing. Lines could be to close to exhaust manifold

check your timing chain

and your ignition timing

Have you check the carb? Is fuel being delivered there? You could have carb problems. Begin checking there and work yourself backward.
