Yep that was EXACTLY it!
Pulled that Diode made a tiny jumper and my unit is back online via USB power like it never happened.
I may order another diode for it on my next order with Mouser, I just dont want to have to pay shipping for that dumb $0.20 part.
But for now I'm back in action, and I will try not to do anything stupid until I have that diode replaced.
Here is the pic of my repair for others that run into this issue...
PS: This is V3.0 Nano
