      more than likely, it's a crack in your pickup line in the tank, once the fuel drops below the crack, the pump starts sucking air (stall).
      Trees aren't kind to me...

      currently: 2 88Ls (Scrappy and Jersey), 88LX, 90L(Pepe), 91L, 91GL (Skippy) 93 GL Sport (the Mighty Favakk), 94 (Bruce) & 95 Aspire SEs, 97 Aspire (The Joker),
      94 Justy 4WD, 87 Fiero GT, plus 2 parts cars. That's my fleet.

            His car is FI, as per this thread.

            Claude, did you pull the pump/sending unit and check for leaks/ cracks?
