truck randomly shutting off

[master_tsoi]

for the past week or so I've had an odd issue with my truck, it would randomly shut off for a second and come back on. its only happened a couple times. it first happened when I was driving forward maybe 5km/h with very little gas in the tank. don't know if this could be the issue. the other day I was reversing and it shut off and again yesterday driving forward. I tool it to the dealership so they can diagnose it. nothing. no issues with the ecu or any wiring problems. has anyone had this type of problem? I drive a 2015 Sierra so its not even a year old.

I had the same thing happening to my 2005 Trailblazer EXT. No codes popped up so they couldn't diagnose why it was happening. The throttle body was taken off and cleaned, new plugs, wire connections were cleaned and it kept happening. It happened more often at stop lights and stop signs, turn the key and the truck started like nothing was wrong. Occasionally it happened while driving except after it died it restarted by itself. It's the main reason I got rid of it to buy my 2011 Silverado. I was afraid it was going to eventually die and not restart, especially hundreds of miles away from home. Good luck, hope you have better luck getting it resolved.
