I've never been a fan of the wiring quality on a Vic.
As others have indicated, check the obvious and easy stuff first. Turning the handlebars would not have a direct effect on the battery connections because neither stretch that far but it's still a good place to start. Make sure it is fully charged, operating properly and all connectors at both ends are solidly terminated. While you've got the proper tools out, check and clean the connectors and mounting bolts on the regulator as well. (just because)
As it is an intermittent problem I imagine you will have to get a bit more involved by checking connectors in the fairing and tank areas. It's very easy to do. You aren't making any modifications or strange repairs, you are simply opening and reconnecting the plugs.
All of them should have locking tabs so make sure they are disconnected properly to avoid any damage. You are primarily looking for a loose connection but also take a close look at the pins, both male and female, for any kind of discolouration that could be corrosion. If you find any, clean them. Also add dielectric grease to all the pins before you plug them back together.
With everything apart, turn the handlebars back and forth and look for obvious problems. Also look for locations the wire moves and rubs against another part of the bike. There may be a bit of worn insulation which could also be a source of both the stalling and low battery instances you are experiencing. If you do see any potential problem areas they need to be inspected closer for physical damage.
As an FYI I had a headlight that would flicker while riding and sometimes at start-up wouldn't come on at all until it got a good whack. It came down to a connector on the aftermarket VictoryHID ballast not fitting into the stock connector as tight as a sealed connector should . It was locked in alright, it's just a mismatched plug that loosely fits and wobbles. A bit of tape fixed it up and it now works fine. That's the kind of stuff to look for.
Hopefully the problem is fixed with this minor amount of troubleshooting. Anything more advanced would need more resources and knowledge on the system. If you have that ability then go for it. It's a good time of the year to have the bike down although depending on your weather, you may not get the opportunity to test it out on the road.
If your problem was found and fixed and before you put everything back together, if during your earlier inspection you found any locations that had wiring moving against another part, it needs addressing. You need to isolate the wiring with cable ties/electrical tape/loom sheathing, whichever is appropriate for the situation.
Good luck and let us know how you make out.
Not all those who wander are lost.
