Give us a little more info about your truck.

Engine: V8 or L6?
Is it completely stock? No added stuff like electric fans, a/c, etc...
Hei or regular distributor?
External voltage regulator or has it been converted?

Here's some of the things I would check.

First and foremost, I'd make sure I have good clean ground from the battery to the block, to the cab, to the frame, and to the radiator support.

Check the cranking voltage on the battery. Meter across the poles to see how much drop you get. (Dragging starter).

Voltage to the distributor when the engine is cranking. (Starter may be draining you voltage.)

Check the fuses to make sure they're not rusted and corroded and also the wire from the ignition to the distributor.

If its HEI isnt the wire supposed to run from the dis to power with the key on?... not directly to the battery.
