Thanks for the reply. Actually the condition shown is when the engine stalled. I looked at engine speed and the rpm,s were zero. This is one of the problems that I am chasing. It acts like I'm running out of fuel, but pressure is rock solid. I drove around with a gauge in the cab and there is no movement. I even turned the pressure up, but this did not change a thing. I checked all the usually suspects, pump fuel filter OPS and the entire circuit. As soon as I learn how to log correctly I will be able Identify or eliminate possible causes. Thanks again.
