Do the separators that the VIP receivers use ever-go bad and if they do what sort of symptoms are displayed? My diagnostic screen shows one tuner has triple figure lost locks when compared to the other that has just double digits.

Separators may be the biggest point of failure item in the IF circuit.

The indicator is usually that one tuner will have decidedly different signal numbers than the other. That being said, the problem may be elsewhere but separators are relatively cheap to try.

Testing the tuners with individual runs from the dish/switch is where you go with suspect tuners.

Also, if you see a problem on only one tuner, flip the separator connections so each side is connected to the other tuner and see if the problem moves to the other one.

Aren't the outputs dedicated to a certain numbered tuner?

FW expecting get some polarity at low L band (950-1450) and some at high (1650-2150) ... perhaps it's flexible enough to discover inversion, but who knows - test it and tell us

No, you can easily flip the separator. It's a really good test if it's the separator/cable or the tuner card in the box itself.

Flipping the separator gave me a complete loss if signal error on an otherwise functioning ViP622.

It may be that you're wrong or it may be that my dish stops functioning because it has lost power (SAT port 1 on the separator is the power passing port) or both.

At this point, I'm inclined to say that flipping the separator doesn't work with a working system, much less a questionably working system.

Technically speaking, against your theory working a fact: connectors on the separator and on DVRs clearly labeled as Sat1 and Sat2. So, it would tell us - FW is not capable to handle cable's inversion.
