I had this problem when there was an obstruction in the delivery line.  That
obstruction was a 90 degree bend!  No wonder I kept blowing fuel pump fuses!
Anyway, check to see that you do have no problems anywhere in the delivery
line, and chekc the fuel pressure if you can.  You might also replace your
fuel filter, if it is clogged then the pump is having to work harder, and it
may not be getting enough pressure to begin with.  Also, might be sediment
in your gas tank.  Hope this helps...
