If you only had 3 gallons of gas in the tank when it was stored, it's possible that you could still have some condensation in the tank even though it was in a heated area. Once you stated the engine and ran it for some time, that could have clogged the injectors, or the fuel pickup sock in the tank. Add some good injector cleaner and pull the fuel pump/pickup to see if it's clean.
A lack of correct fuel pressure can cause what you are seeing. Are there any air leaks or opening in the intake air ducting? Also check the TPS for any binding/sticking.
