Dandy. First of all, forget the battery gauge on the dash. That is nowhere accurate enough for doing any type of diagnostics. They are notoriously inaccurate and their only real value is to the person who regularly drives the vehicle and will recognize when it indicates something different than what it normally does. That's also why they don't have numbers on the entire scale. The difference between a good, fully-charged battery and one that's good but totally discharged is only 0.4 volts. You'll never see that minute change in the gauge reading. To get the accurate "state-of-charge" reading, you need an inexpensive digital voltmeter, and the reading has to be taken right at the posts on the battery. If you don't have a voltmeter, you can find them at Walmart, Sears, Radio Shack, and any hardware or auto parts store. Harbor Freight Tools has a perfectly fine one that is usually on sale for less than eight bucks.
Second, since the starter is cranking the engine, the battery state-of-charge is not an issue. The confusion here is you originally said it "won't crank". A lot of people confuse that terminology to mean the engine fails to start and run. "Cranking" and "turning over" mean the starter is spinning the engine. Whether it starts and runs is a separate issue. "Cranking" is a leftover term from the days of hand cranks to start engines.
The water in the tank is almost certainly not related to this sad story. It has been run through the engine by now, and any problem it was going to cause would have occurred long before now.
The first thing you have to do is determine if you have spark. Next is to determine if the fuel pump is running during engine cranking but this is more involved. The one or two-second hum you hear when you turn the ignition switch on tells us the pump is operational, but it takes a different set of circumstances to turn it on again when the engine is being cranked. If you do not have spark, it is pretty likely the pump isn't running either at that time, but that is only an additional symptom or clue, not the circuit that needs to be diagnosed.
You listed two different symptoms for the running problem so please clear that up first before I wear my fingerprints off on this keyboard. "Stalling out" and "acts like its not getting gas" implies the engine is running but poorly. At first you said, "it just started stalling out and now wont crank" which I think you meant the engine won't start up or run at all.
