2009 Chevrolet Equinox engine problems

I was recently in a vehicle accident. My vehicle shut off as I was driving and in route of a traffic light. As a result of my vehicle shutting off, I had no brakes and was therefore unable to prevent my vehicle from proceeding through a red light. I then hit a tow truck and was t boned. My vehicle was totaled as a result and myself and my 2 children were transported to our local emergency room due to injuries. Previous months I've had a issue with the vehicle shutting off while driving.

I was driving at a speed of 40 MPH when I slowed to make a right turn. The stabilitrak notification stated that it was "off trak" and to service "traction control" and that "engine speed is reduced". I could drive no faster than 5 MPH. I pulled over and turned my car off for a few minutes. When I started it back up the speed was normal again but the engine light remained lit and solid. This is the second time in 2 years that this problem has occurred.
