I would inspect the battery cables very carefully for a broken wire.

Sure sounds like an intermittant wire or connector somewhere. Considering
the MILES of wire in a modern auto, good luck!

Also, check the Fusible Links...one may have just worn from age, but
hasn't quite snapped yet, or the isulation is JUST holding it together.

This is NOT going to be fun! You'll have to check a LOT of wiring, but
given the symptons, you're looking for something VERY dlose to the start
of the electrical system; wiring to the battery, alternator, the Links,
the fuse block under the hood and the connectors under the hood.

Try jiggling, re-connecting, etc with someone turning the key occasionally
to narrow it down.

I'd use some rubber insulated gloves and goggles while doing this chore,
myself...

Also check the wiring to/from the key switch, and the switch itself.

...

Besides the suggestions that others have posted, check the ground for the
fuse boxes under the dash and in the engine compartment.

The Electrical Manuals usually have a Power Source tree-like diagram.
This used in conjunction with a table of symptoms can lead to a specific
'branch'. The same documents have location information for all electrical
components.

I don't get paid for this (and that's not a hint)...
