First time breaking down, Possible problems Options

Ok so last night my car decided to take a dump on me, everything was running smoothly then when I came to a light and tried to accelerate my car started sputtering and went very slow no matter how much gas i tried giving it, after about 20 feet it just died. She still cranks over and it sounds like it sputters but doesnt fire up. I tried using my scanner to see if any codes came up but nothing, so my initial deduction is probably the fuel pump but i'm not ruling out the ignition system, any ideas what would cause it to do that before dying completely?

Start with the ignition system -- pull each sparkplug, ground it and crank the engine. If you get adequate spark, you can move on to the fuel and air systems, though if your plugs are wet with gas after cranking that is a good sign the fuel system is working. If you don't get adequate spark, then you start working up the ignition system until you reach a working component; the component prior is what has failed.
