What would cause just this one spot in the fuse box to go dead at crank but not at key on?

You need to test voltage at the ignition fuse or any marked "battery". Most accessory fuses don't have voltage when cranking, just at "key on". The only two places that would show voltage when cranking are the battery fuse and the ignition fuse.
