Injectors 1 & 2 dropping signal rapidly and intermittently, with #3 injector losing signal for much longer duration; sometimes days before it starts working again.

Besides the injector harness, what's the common equipment, etc, to these 3 injectors that could be causing this?

The pcm
All the injectior share the same power wire

I'd start by checking wiring ... Connectors..ect...
Then look at the pcm

Good info. Thank you.

Do I have this right: all 6 injectors are spliced into the same, single, power wire?

Would that power wire be within the harness that's under the lower intake, or could I find that power wire without removing lower intake (no garage, 15 degrees outside today)?

Thank you again

Yes
You can check at the pcm connector and injector connector
Here is a picture of under the intake
