Hi my name is***** will be glad to try to help. Does it shut down instantly like you turned off the key switch or like it is starving for fuel? Is the check engine light on and if so what do you have logged for fault codes?

Thanks for the update. When you first turn the IGN switch on the check engine light should come on and cycle with the key. Let me know if this is the case. IF not the ECM is not communicating from either a loss of power and ground or an ECM problem but I see you replaced it already. Be sure the ECM software was programmed with the correct settings and the most current updates for your engine serial number and truck configuration. Let me know. Also be sure the ECM is getting engine speed signal from the speed sensors or the injectors will not be commanded to fire.

Is the tach working consitantly or are you loosing tach signal when this happens? If so it could be a loss of engine speed signal which does not always throw a code.
