What PS (or other) condition becomes 'reset' by such a power source
interruption of sufficient seconds duration?

It sounds like the PSU overcurrent sensing is tripping. Once it
trips, the only way to reset it is by cutting the AC supply to the
PSU, by unplugging it, or using the rear AC switch. The over-
current tripping could be due to a PSU, motherboard, internal
peripheral (drive), or a wiring/connector fault.
fault.

I'm now reading that "Most computer power supplies have short circuit
protection, overpower (overload) protection, overvoltage protection,
undervoltage protection, overcurrent protection, and over temperature
protection."

.... along with the potential for the logic or circuitry to 'think' such
protection should be employed in the form of a shutdown which also
requires reset.

I might have an overabundance of protection here.
