Customer Question

I have a 2009 international Prostar, with a cummins ISX. When bob tailing, or with an empty trailer, everything is fine. Under load, though, the inverted triangle lights up and the display reads "Warn Engine". While in this mode, if I accelerate hard, DEFCON 4 occurs (red stop engine light blinking, incessant buzzer, small children crying), yet the truck continues to run smooth and strong. I think that it's a fuel starvation problem. Ideas?
