My 2008 Peterbilt 388 with a Cummins ISX is doing something very strange. When taken to 1400 RPM it shuts down and throws the check engine, stop engine, abs light, and every every other warning sound and light it can throw. If I take my foot off the throttle after a few moments it kicks back on like nothing.
When it shuts down everything goes, the engine, the gauges, everything.
So far we have replaced the ECM, rewired the ECM power and ground, and checked a few fuses to no avail.
