Electrical fault/ abs module

I’ve read a few threads so sorry if I missed it. My truck suddenly shut off while driving, and light came on and lost all power. Let it out of gear and it shut off. I can get it to turn on randomly but rarely. Sometimes it barely gets started and abs light flickers and it shuts off. Screen reads abs module and sometimes electrical fault. When it reads both it’ll only crank. I got it to idle for a good while with no messages, but it only drove for maybe 10 min before it shut off. I don’t even know where to start or if this is something I can look for on my own stranded on side of the road. Already checked fuses, body control module, 100 amps by the firewall, I did have battery cables go bad where the cable was heavily exposed. I’m wondering if I shorted something out. Someone is telling me my ecm is toast. Anyone had this experience before? Am I missing something simple? I’ve gone thru something similar and guys had to reprogram my bcm. Can they reset somehow?
