Motor won't spin, can't find the problem, please read and help

Ok, got my f550 up and flying. While hovering back and forth, I would notice a sudden dip to one side ever few seconds or so. I was only a few feet off the ground, when I noticed one of the props stopped spinning, and the craft became unstable, and slid into a hard landing. Upon inspection it looked as one of the motor to esc connections may have been loose, but none were unconnected. I pushed them all back in as best as possible, and tried it again. 

This time however my number 2 motor wouldnt spin (only will spin like a 1/4 turn every few seconds or so).  I posted on the forums, and it was suggested my solder connection might be bad. 

When I made it home tonight, I took things apart, resoldered my connection, put back together and tried again. No luck, same thing happening. I have a spare motor and esc, so I first swapped the motor out, same thing happening. So then I unsoldered the esc, and chanced that, still no luck. 

So thinking it might be the Naza, I swapped the connections for motors 1 & 2, same thing happen on same motor. 

My only conclusion is it could be a bad power distribution board.  Does that sound like a possibility? 

Any other ideas?

Thanks for the help,
Jeff
