I was reading your post and sorting through the various diagnostic angles available based on what is known..... Then I got down to this part:
"HELP! Our prepair bills to date are in excess of $10,000 and about to climb higher"
And a stiff chill ran up my spine, stifling further thought on the matter.
If it helps.... I still have you beat in terms of dollars spent... oh! and I did all the work myself, so the $11grand dumped inside of 2.5 years was just for parts..... wholesale parts.
Ringlee summed it up. We need more information. At this point if I had to chase something.... I would be looking for a stuck injector. The distribution rail holds 30-40 psi even when the electrical system is off. A stuck injector will allow raw fuel to pump into one cylinder, down the pipe and into the cat where it will pool and soak the honeycomb. On restart, as the catalyst heats, you will have a hell of a furnace going down there for a minute or so. But then it cleans up and the dealer can't find it.
If you can't find the cause quickly, you are in a stop-loss situation. Dump that piece of shit and move on.
