78 seville 350 5.7 efi..car stalls and turns off when going uphill but runs fine when driving on flat or downhill..PLLZ HELP this is my only means of transportation for me and my family!!

how steep of a hill and has there been any work done on it lately?

its not too much of a hill but is decent..the car has been having alot of fuel problems lk the rubber hose that is on the fuel pump was split down the middle so it was sucking alot of air so it was replaced and the computer for the fuel injection was replaced..the resenator went out..it was sittin for about a year before i got it "running" any ideas??

check fuel pump, blow out fuel lines, check fuel pressure
