I would say that most of us would agree with the course of action Leonard has laid out for you to pursue.
Also, below is a good link on the details of "back probing" if you are interested.

Given the age of these vehicles now, wouldn't it be easier, and a more thorough repair to just replace the wiring harness and be done with it instead of all this back-probing, then trying to unravel and repair? I bought a wiring harness ten years ago as a hedge against a day like this for myself.

The bowl heater hasn’t been plugged in for years.
Last year I only replaced the injector solenoid on #6, not the injector. Its interesting to me that with all the codes, 6 isn’t having any issues. 2, 4, & 8 have codes.
Tomorrow I’ll have some time to tear into it and see if there’s anything obvious in the valve cover.

Based on all the codes, I decided to start with a new injector solenoid on #8. That seemed to eliminate the worst of my issues, but it would still occasionally shut off on its own, just like I turned the key off. With the number of codes relating to harness issues, I decided to just change the valve cover gasket since I had a new one on the shelf. Just for kicks I also figured I’d change the CPS out for another new one.
Problem solved. 200 mile/4 hour test drive without a single hiccup. Not exactly sure which part was the culprit, but it’s running great, so I don’t really care at this point.

Most likely the contacts in the gasket between the UVCH and the engine harness were faulty or loose. As you mentioned, no matter now.
Good news on the easy fix action and thanks for closing the loop.
