First thing I would do is check all your connections from the battery , alternator, and starter. I bet you got a loose ground somewhere.
Makes sense actually I never thought about it but I could see that as a cause.My 2004 DC does the same thing every now and then. In my case I think what ever switch or mechanism that lets the truck "know" it is Park is the problem. I can turn the key multiple times and nothing happens. Then if I barely bump the shifter toward Park, the engine starts right up on the next try. The dealer told me it was the ignition switch/lock cylinder assembly but I didn't quite buy it. Any thoughts from anyone out there?

Under the manifold? that sounds like a total PITA.Had the same problem 6 months ago. The starter contacts were corroded. Replaced both and now runs fine. Wait til you see where the starter is located. You have to take half the engine apart to get to it. It's conveniently under the manifold.
That is only the case if it is a V6. The V8 is a whole nother can of worms. You have to remove the intake manifold and the fuel rail (all comes off together) and then unbolt and remove the starter.easy!! its the starter.. happened to me too.. couple bolts and it comes right down. .
