It seems my truck has a mind of it's own, I put the key in and it starts most of the time. Sometimes it starts and shuts off after a couple of seconds. I try to restart an it cranks and cranks no start. I wait a couple of minutes it starts. So I spoke to some people and they thought it may be the chip in the key or the skim reader module. So when I got a no start I would pull the key out and reset it in the ignition and it would start. I took it to the dealer and had the skim module and key replaced, everything was good until yesterday I got a start couple of seconds die, no start, pull the key reinstall it start. Any suggestions?

 

Sounds like the auto shut down relay... possible ignition switch also. Inline a test light to start relay from switch and check continuity as you cycle the key and try to replicate the issue.
