I've seen an intermittant 2AG fuse twice, Drove me nuts the first
time. By intermittant, I mean it would open in circuit, but would
test OK with an ohmmeter.

** Yep.

Typically, the fuse wire has come loose at one end - or was never soldered
in the first place.

It looks fine and has continuity due to light pressure contact alone.

When the wire heats under load, it opens and closes.
