GMC Canyon dies when driving

I have been having issues that no one can diagnose. Hopefully you can help.

Hi Scotty,

I have a 2010 GMC Canyon. Great shape- i am second owner mileage just turned 80008. No problems were reported
prior to my purchase. Issue- when driving early AM- within 15 - 30 min engine dies- power still shows on dash/lights but engine shows no power (like I turned it off)- Air Bag indicator comes on- no other lights. If I can't pull over (mostly) while still rolling- I put in Neutral & bump the key to on- it starts back up- this happens in traffic- not safe. This has happened a couple of times during the week, then stops. When I complete the rolling start in Neutral – all indicators come on as if I just started the motor. No Stalls, no sputter. Have not found any Air Bag recalls, engine recalls. No test indicates anything. I have spent 300.00 + trying to figure out what is happening. suggestions?

Thanks so much. Kimberlie
