Ok about 2 months ago I had my security light flash for a few seconds while driving, but nothing happened. A month ago while driving my truck just cut off I did notice the security light flashing, when I restarted the truck it ran fine no lights on no trouble codes it has did the same a couple more times. This morning while driving it started to stall out and did stop running, security light flashing and engine light on, restarted and ran fine. Info on truck 2012 Colorado crew cab Z71 5.3 engine with 70k miles. Where should I start to look to find the problem ? Or is this a common issue ? Thanks in advance for any help.
