Following up .... it happened again, and I have a bit of egg on my face, so to speak. I was whining about electronics, turned out to be the starter after all.
When it happened I tried all the key sequence stuff, no luck. I rapped on the starter, still just a click and nothing. I called AAA for a tow and the guy was willing to rap on the starter while I tried the push button multiple times, after a few tries the starter groaned slowly to life and started it. Was pretty obvious at that point, instead of a tow I drove and dropped it at the dealership. The AAA guy followed me and gave me a ride back, I have to say I've had great service and some really great guys when I've needed to use it.
At the dealership they said unfortunately they see a lot of starters being replaced on 2500's without a lot of miles on them (I have 69,000).
So the good news is I don't have anything electronically wrong.
