I suspect that in this failure mode it will be necessary for me to once again load the "output_file.pof" into the EEPROM using a blaster cable and the Quartus II Programmer to recover. 

Note though, Joe, that it's a failure mode that just shouldn't occur at all.  So if it happens again, it's probably indicating some sort of hardware failure.  My thoroughly uneducated guess is that you might have a flakey flash chip on that board that's losing its brains.  Or it could just be a transient cosmic ray that flipped a bit somewhere.  My point being that if it happens again, I'd go into "my hardware diagnostic mode" and run down the problem.
