2007 International 9400i powers off while driving

My truck runs good, we’ve reflashed our ecm, however, since then that we’ve taken it out to work it’ll turn off like if we turned the key, and while otr it does this. Antifreeze is fine so are the batteries I’m not sure what else it could be. If anyone knows about this please me out. Its a 2007 International 9400i with a Cummins ISX.

However, I ran into a dilema when I discovered that each little prong that goes into the conector all have ground. I know that the ecm is losing power, we switched a burnt out lug on our battery, we switched the main power harness, and traced wires. What should I look into next ? Also, the ecm connector has both the main power wire and the optional power wire, while the power only has the main ground and not the optional. Why would the ecm only be receiving ground ?
