Well learned a lesson, the ESC has three wires, signal, ground and 5v, the 5v is a BEC regulated output, not an input, I was hooking that wire up to the 5v out pin on the FC. might explain why i had so many off problems like the CLI screen locking up. I am going to retire this FC. I have a new one coming tomorrow. I am not going to use the BEC +5v for anything so I will just leave them disconnected. Lesson learned!
