I would definitely start with connections. It could be loose connections. Is your battery fully charged? Before you spring for the coils make sure you have good voltage.

I have just rebuilt the carbs on my buddy's Bandit 1200 that had a similar problem. After doing the initial checks to confirm it was not plugs, wires or coils and doing a compression test it came down to the carbs. After removing them and taking the float bowls off I found lots of small rubber pieces in the bowls. This could only have come from the rubber fuel hose, from tank to carbs, as there is a filter in the fuel valve in the tank and that was clear. The small rubber pieces had blocked off some of the jets. Apparently Suzuki recommends replacing that hose every two years. I suspect alcohol in the fuel was eating the inside of the hose.
i am not saying that is the same problem you have but something to keep in mind. If it had not been stored with fuel stabilizer in the tank I would drain the fuel and add fresh gas and then if the problem persists do the basic tests first before going further.

Check if starter has gone defective. Sounds like it by you description.

seems like the carburetor jets need to be cleaned, also check and make sure everything is secure, maybe the battery is wiggling to much on a turn and arcs or even could be as simple as a fuel filter clog. something to do with leveling so I would say jets

There is a sticker of vacuum line diagram under the seat by the parts bag. It is on the right side rear of that compartment.

Either the vacuum operated petcock is stuck in the flow position as well as a float needle is stuck in the open position. Two things would have to be wrong so that the fuel would over flow the carburetors and run past the piston rings into the crankcase. Or, more likely, the vacuum diaphragm inside the fuel petcock is leaking and the fuel is flowing down the vacuum line into the engine. I would start by inspecting the vacuum fuel petcock. If you unplug the vacuum line and gas is dripping from the vacuum line then you will need to rebuild or replace the fuel petcock.

Bear in mind that even without the engine running there may be a number of things drawing power:

The ignition coil will be powered up
Does the bike also have permanent running lights on as soon as the ignition is engaged?
Your neutral light will be on (only .2 of an amp)
Does the bike have an electric fuel pump?

All these things may add up. You are only drawing about 25 watts, which is the power it takes to illuminate a brake light.

While I don't have data on the power consumption, it doesn't seem that excessive
