Why does car keep stalling

I have a 2004 Jetta GLI that I recently replaced the fuel pump. It drove great for 3 days afterwards, but now I can even drive it to the end of the street before it stalls. It always restarts but will stall out again as soon as you start driving. Can anyone help with suggestions?
