Sounds like you might need to protect the starter with some type of "heat shield" to prevent heat soak------GM made them not sure for which vehicles newer vehicles probably have them--- ALSO as old as that truck is(30 years) and the hi miles (300,000) I would replace both the positive and negative battery cables also check the chassis ground for the negative (is it nice and shiny or is it real rusty?) install an additional ground strap from the head to the chassis ---Actually First thing would be to check your voltage at both ends of the positive cable (starter end and battery end) should be like 14 volts if there is any difference you know its in the cable might be terminals or the cable itself ---it takes a lot of voltage to run a cold starter but when it gets hot it needs even more or all it can get--- just a few suggestions---FED 387
