1994 Standard Transmission Truck only 122,000 miles it killed on me backing

What is your question?

No power at all. Dead had the battery checked it's good. No power at starter. Jumped the starter straight from the battery and it started. Truck runs good, but as soon as I turn on the headlights or press the brake it dies. During the time the truck runs all dash gauges work proper. No warning gauges are on.
