Kill switch ON? That was also the first thing I thought of.
The sidestand switch is easy to check: put the stand up and if the 'S' light goes out then the switch is ok. Also, with the bike in neutral and the stand down it will still start.

start by checking fuses, if the was a electrical issue as sudden as this it is a good idea to start here. Then check your kill switch and sidestand switch to make sure they actually work. You will need a multimeter if you don't have one already, its just about the only way to troubleshoot electrical issues. Start with the obvious and report back.
What I mean by that is I believe you when you say the switch is set to run, but that doesn't mean its not faulty.

Checked spark - at least on the front cylinder - looks like its there. So that seems to rule out electrical. Checked fuses as well. So maybe a fuel problem? Funny, one of the fuel hoses was totally filled with gas when I took the tank off. Don't know if its getting to the carburetors.
Considering pushing it 7 miles to the nearest Honda dealer.

If yes, you need to check all your connections to the tank are proper. The most common error is people connecting the little tube to the lower nipple on the petcock without looking for the proper connection farther back. After you take the tank off a couple - three times, then you get it. It's just a vac line but it's got to be in the right hole.

Make sure you don't have the little hose that goes into the bottom of the tank reversed with the one that goes to the back of the petcock. They are approx the same length and diameter and could be inter changed.

If you have spark then then I would be back to fuel for a while. You need to make sure that the carbs are receiving the fuel from the tank, and there are two things that will stop that. If you have turned the petcock off then that is one possibilty. The other is that the vacuum hose mentioned above may be in the right place, but is it providing vacuum to the petcock? Check that it is. The other option is that the petcock diapragm is broken. Both of these will cut your fuel off.

I doubt that there is a hose connection problem, since it was running good for the longest time, didn't mess with anything, then suddenly crapped out. It appears to me that fuel is flowing from the petcock, cuz the tubes have gas in them.

They won't be empty even if fuel is not flowing, it will have to suck air to be filled with air, so don't assume the carbs get fuel because the hoses are filled with gas, they will be anyway.
Take a 2 $ syringe and pull vacuum on the petcock, if gas pour out, it works, and verify that the vacuum hose running to the rear cylinder is not cracked or pinched.
To check spark pull the plugs hook the wire and rest it on the frame/engine.
Compression, well you just can listen to it cranking, if it stumbles every compression (normal), otherwise it's abnormally smooth.

That's odd, since cranking is the first thing that would be affected by a low battery. Was it cranking at normal speed, or slow? It may ultimately be a R/R problem.
Can't argue with success though, batteries don't last forever....go out and ride it.

Ya, it seemed to crank fine for me, and it was producing spark. I have experienced many a car battery go bad, and the first sign is it doesn't crank. I gotta quiz them more tomorrow when I pick it up.
What is an R/R?

Rectifier/Regulator is a known problem on earlier VTRs. It would overheat and fail. Do a search to check it out. Easy replacement.
Rectifier is made up of 6 diodes that change the alternator output from a/c to d/c.
Regulator controls charging voltage and amps.
