fuel pump keeps going out..whats wrong?

i replaced my fuel pump and within a 20 mile drive the car started sputtering again and then died at every light. my fuel pump smells like it burned out again so my question is what keeps burning out my fuel pumps? any help appreciated...

shorted relay sending too many amps?

i agree.

You should also check for a crimp in a fuel line somwhere.
