This problem usually shows up when the soleniod is hot, after about a 10 or 15 minute engine shut down period.

You solved the problem by eliminating the voltage drop. I sovled the same problem by replacing the starter and solenoid (after I proved that everything else was okay). I still have the voltage drop, but now I have a new soleniod that can live with the voltage drop.

Bingo!
That was exactly my conclusion.
Try as I might, I could NOT find a single reason why it wouldn't crank the starter.
I checked everything I could check with my limited skills and diagnostic tools and I could not find a single failed component.
And to add insult to injury, after an undetermined period of time, the goshdarned thing would just fire right up with a turn of the key.

So, it was my conclusion that it wasn't a single problem, but instead a combination of little problems that caused my Dreaded No Start
(I capitalize and bold it because of how frustrating getting stranded can be, only to have it start for no good reason a little while later and make you look like an idiot in the mean time)

In my daytime life, I run and repair very sophisticated laboratory equipment.
I won't bore you with the details, but I've learned the hard way that an intermittent problem is the absolute WORST kind of problem there is.
In the world of electronics, if you let out the magic smoke, the failed electronic component is fairly easy to diagnose and repair.
If the !@##$%% piece of !@#%%^ won't fail completely, it's nearly impossible to diagnose and repair unless you're lucky enough to see the fault first hand.
I've seen it twice, got stuck twice, and had to call for a lift home twice.
I WON'T SEE IT AGAIN.
The next time it fails, there better be Magic Smoke, or I'm gonna be pizzed!
