Sounds like a fuel pump issue.

Have your filters been change at regular intervals and do you use the OEM (Motorcraft, Racor, International) filters?

In addition to the HFCM (pump) issue (as was previously said), it could be issues with solids plugging the intake tube, and it is also possible that your fuel pressure regulator is sticking (poppet style plunger).
