s2vsb=1(ShortToSupply_B!) but file triggered !??

started getting skips... so bumped up the temp a hair. Then slowed the print speed. Finally pulled the stepper motor on the extruder and bench tested it .... ehhh fuzzy... doesn't 'seem' to be bad, but not right. ... Amazon the to the rescue...brand new LDO-36STH20-1004AHG(XH) , mounted.
20 minutes in.... SHORT error and shutdown . So I swap the 2209 on the Octopus Pro 426 and restart the print. Dies in 20 minutes... but the klippy log this time is throwing errors of some file name line number issue statements? So...might I have flaky RPi memory, a crappy SSD my VC500 and RPi4 8gig boots and runs from? I beat the hell out of my umbilical, but no changes is connectivity or shorts. ...clues what to look for? see attached klippy log segment two sections...showing the file name scripts involved thoughts? flames? ideas? tia
