have replaced fuel pump several times, new pump lasts about 6 weeks then drops fuel pressure from 90psi to 45psi, have changed filter, runs great with new pump, replaced pump atleast 8 times, what could cause this?

Check your ground circuit for loose, corroded or broken connections. All the way to the battery.
Assuming you changed the filter have you checked the fuel pressure regulator.If not those maybe its gettingsometypeof power surge is the sleeve clean when u change it?
