My Orion-II had exactly the same symptoms, on a couple of 
occasions. The master resets helped for a while, then the same 
problem came back. Looking at the DC power cable connector, it was 
fine. So, I opened it up.

The first thing I did was to replace ALL the electrolytic 
capacitors on the A9 power supply board with high-quality 105C 
capacitors. I then checked both batteries (CPU & AT), and replaced 
them. The last thing I did was to DeOxit ALL connectors in the 
radio (quite a job). It has never had a problem since.
