If you have no power anywhere at all, then it sounds like it would be either the solenoid or in the battery cables.
I have seen batteries die suddenly, but as long as the alternator is good, it shouldn't be a sudden death to everything.
Do you have a meter so that you can read what the power is on various locations, such as the battery, at the solenoid, frame grounds etc?

Here's another possibility... an antitheft system.
They go out or burp and you will have the same effects..

I had the same thing happen in the middle of rush hour going home traffic, yep going up hill too, in a 71. Turned out that a couple of wires entering the voltage requlator broke off from old age and I had been running off the battery alone until it just died. No emergency flashers, no jump start, nothing. I installed a new voltage regulator, sillynoid, and of course, some new wires, charged the battery, and it ran perfect.
