Hi Guys. Thanks for existing here . My 07 6.2 Denali runs like a top... for about 20-25 minutes then starts misfiring and dies. The dying part takes about a minute from start to finish. Replaced fuel pump. Fuel pressure at the rail was about 25 psi too high and thought the pressure regulator inside the pump went. It seems coasting and stopping piss it off once the motor is warm. Once during its four deaths it threw codes p00011 p00172 and p00700. If this issue is already solved can I be pointed in the right direction to the thread All the best to u all
