Often times a vehicle sitting for an extended length of time with less than a full tank of gas will tend to condensate moisture from the air. This generally will accumulate at the top of the tank and virtually rain-shower down into the tank over time. Filling the tank with gas causes the water to intersperse with the gas but will eventually settle to the bottom as gas is lighter than water. You now have water in your fuel system and your gas tank where it will very soon start to rust creating all sorts of havoc with clogged fuel filters, etc. There are a couple of simple solutions to try first, try a very high concentration of isopropyl alcohol...hospital grad of 95% is best. This will bond with the water and combine with the gas to form a 'burnable' liquid. Since it sat so long, you may need to go a step further and try another pour-in solution such as Sea Foam.
If that fails, you may have clogged injectors which requires a bit more effort. There are injector cleaning kits that run about 100 and hook up to your fuel rail. Most of these inexpensive fixes will not remove rust debris from the very fine filter found atop an injector body.
Additionally, I am a bit concerned that you may be experiencing an electrical problem that is summarized in a recall post at:
