04/06/2017- I took it in dealer and technician looked at it. It is not showing any codes and he couldn't find any service bulletins about it. He checked a couple of things and everything checked normal. So, I took technician with me on a ride and he had laptop connected to car. Sure enough, in first gear at WOT it totally cut power at 5600 RPM. I was actually relieved and he was able to capture the data. They are discussing with Chevy Tech support and it has been made a priority. They are bringing in an Area Specialist in the next couple of days and I will take the car back up there when he gets here. Also, several of you guys suggested ECM refresh or computer related. Local dealer can not refresh codes without Chevy being directly involved. I will keep you updated. I think it has to be simple because it hasn't shown any other symptoms or issues.
