This has started happening more frequently. Not sure if it has any correlation to it getting warmer (mid 50s) here. I can tell when I am going to have the problem because when I click the unlock button on my FOB none of the lights go on to let me know it unlocked (it hasn't unlocked either). If I click it a couple of times it will then click on.
Then, when I get in to start it, this is what happens (video)? It will start up a couple of times, but die right away. Even if I feather the gas it will die once I stop giving it gas. After it starts up and dies for about the third time(give or take), when I start it up it, it runs like there was never a problem?
Seems too fast to be the starter, but I have no clue. I decided to take the video to show the dealer because I have had it in twice now to try and fix it but they couldn't replicate it.
Here's the video, you might want to right click and save as, it's 9M (only 55 sec).

Thanks guys, sorry for the book.

Sounds silly but.....clean your battery terminals. This truck was never in deep water or a flood rebuild was it? From the description of what its doing I would think the key resistor is not being detected by the VATS/BCM. If loose battery connection or corrosion is present and battery power was dropped from the pcm, the pcm is in a relearn mode when you finally get it going. Could be a bad connection somewhere else or even simply a fuse with a weak connection and when a heavy voltage draw hits the connection it more or less arcs to improve the connection. Might check the main power connection from the battery to the cab connection, usually just tightening the nut on the starter solenoid.
