03 5.9 almost ecm brick

Has anyone had a mvp3 fail in the middle of a write then say controller unlocker timeout the truck would not start. After about 10 tries I got it read, it got to 75% and failed with the same message then 10 tries later it wrote a complete tune thankfully. I'm just wondering if anyone has had the same kind of problem or a solution to the problem. Also this the second day I have owned my hp tuner and first real tuner

You have a good batterie on your truck? Sometime voltage is a bot low

My mpvi2 times out all the time on 03-05 trucks.. just have to keep trying until it actually goes through
