I have. The truck listed above is a 3500 Duramadre diesel. Several times this has happened. Upon acceleration the motor trips and shuts off but cokes right back to like nothing happened. I have changed the fuel pump, put in 2 new batteries and even changed the computer. Today it did the same thing but shut down and did not start at all. Nothing works when I turn the key. I’ve watched videos but can’t seem to find really the same issue.

I would start by checking the fuses.

Here is a guide to help:

If the fuses are okay, it sounds like the BCM is going out but to be sure let's run a CAN scan. you can get a CAN scanner (Controller Area Network) which will work on most cars from Amazon.

Here is a video to show you how:

Here is how to change the BCM out in case you get a code for it, you can get a preprogrammed unit by searching Google or Ebay. Check out the images (below). Please let us know what happens.
