Before I answer the question, I suggest contacting EricVanWyk, who helped design the PDB and is far more knowledgeable about troubleshooting it than anyone else here on CD. That being said:

Just to make sure there's no confusion at all, this means the light turns on when there is no fuse present and there are no wires connected, correct?

This sounds like a power issue with the DLink; have you made sure that the barrel provides a secure connection and that the converter is hooked up to the dedicated output?
To reiterate Alan's question, how long does it take to reestablish communications? You may also want to observe the DLink lights when you ramp up shooter speed and see if they turn off; if they do, then you know you're having issues somewhere in the power connection.
The new DS allows you to graph the voltage over time; have you tried identifying a voltage threshold at which your communications cut out? Seeing as how the dedicated input is designed to function down to a 4.5V battery, I doubt the PDB itself is your issue, because it takes a massive load to cause a voltage drop that big.

Could you clarify what happens when you do what? i.e.
- Does adding a fuse, 20A or 30A, rectify the problem?
- Do you push down onto the fuse itself, or somewhere else near the suspect slot?
IMO, there are metal shavings and/or a bad connection in your PDB, which would explain the errant light and intermittent connection.
