2014 Volt Shutting Itself Off on the Street

My wife was driving my Volt while I was traveling on business (as she usually does) and she mentioned that the car shut itself off while stopped. Has anyone else experienced this?

I know about some hitting the power button twice by mistake to go to the Sport setting but this was not the case here.

Lauren from GM has been great in helping me schedule an appointment with a dealer which I am taking the car to on Monday for other things like the clicking sound while turning on the front axles, creaking sound on the rear suspension, infotainment resetting itself or lagging, overly sensitive forward collision system (constantly warning of an impending collision when there isn't even a car in front of me) and a small trim piece that fell off. I will add this to the list.
