why would my truck be running down the road and all of a sudden just shut down.

What is your question?

No dash lights, no response at first when key was turned, then would fire and quit several times. After about 15 minutes started and ran for a couple of miles and the same thing again, several times. Made it home and now fires up and quits, but won't run. At rimes there is no response at all when the key is turned.
