So my battery was getting tired for a while, 6 months I limped on it. Replaced it about two weeks ago. Everything has been fine. Today left work, drove about ten miles and stopped at the hardware store. I was in there for five minutes. Jumped in the truck and it clicked. Then the relay #2 started clicking and wouldn't stop until I disconnected the battery. No lights, no radio, no dinging, nothing. The gauges a stuck at the pegged position. Any thoughts folks?

Had tons of starting power when I left work. Can a battery die on a ten mile drive if the alt. Quit?

If its a diesel engine, check your heater relay output. It could be continuosly supplying the heater plugs, thus draining the accumulator to vertual emptiness

Not a diesel, but thank you anyway. Got it home by jumping it. Somehow? The anti theft is the problem I believe. I only have one key so I'm getting another one today. Try to program them. I did jump it again at home and the truck killed itself (sounded like a kill switch was activated). I have the dash all apart, switched around some relays, checked fuses and connections, all looks fine. We'll see what the keys can do. Thanks again!
