My Brothers 1995 Geo Prizm keeps on dying on me. I have changed the fuel filter, and i've sprayed some STP cleaner on the filter of the EGR valve. I know it,s not the fuel pump, i've checked it out alredy. I can drive it for about 5 miles wihout any problem. I can go further as long as i don't stop. But when i stop i have to fight to keep it running. I know this uses a fuel enjector system, but it seems to be fludding out like the old carborator vehicles. Can you tell me what is more than likely wrong with this car?

Optional Information:
1995 Prizm 1.8
