Does anyone know what the issue may be.

I replaced my fuel pump due to it being
weak so the car wouldnt start. After
replacing it the car started right back up. So
I drove the the gas station down the road
from me and it died in the parking lot so I
sat at the pump, started it back up. Killed it
put gas in, started right back up again. As I
was pulling into my wife's work It died again
and no fuel pump sounds. New fuel pump.
However was a cheapy. Before it has sound
at the pump on the old one just not strong
enough. Im not getting anything from the
new one after 5 minutes of drive time.
