Car won't stay started
When gasoline sits for that length of time it turns into a varnish like substance. It gets the consistancy of something like real sticky warm creamy peanut butter. (basically turns to thick sticky muck). Which plugs the pick-up screen on the fuel pump, the fuel injectors and can even plug the fuel lines. Fuel injectors are designed to "spray" the fuel into the intake in a very fine mist. I believe the reason it starts then dies is because even though the injectors are plugged they will "drip" fuel because of the pressure that fuel injection works on. The "drip" is just enough to fire the engine and then die.
What you can do to confirm that the problem is actually fuel related is, using a can of carbuerater cleaner (in a spray can) start the engine while spraying into the air intake. If the engine keeps running as long as you keep spraying, the problem IS fuel related. If the engine doesn't stay running when sprayed. Then the problem is NOT fuel related. I don't recommend using "brake clean" to do this because some brands of "brake clean" are non-flammable. I hope I wrote this so that you understand what to do. Good luck.
