Does it do the same on both tanks or just the front tank? Have you made sure the switching valve is operating correctly? Ford has a lot of trouble with those valves not switching fully, so the lift pumps won't run or the gauge not read correctly.

Located in the frame rail on the drivers side, it will have 6 fuel lines and an electrical plug connected to it.

It could be on the inside firewall just left and up of the steering column, or just behind the passenger side kick panel, it is of interia type so you will either have to trigger the switch or just unplug it, but I have found it easier sometimes just to pull the fuel pump relay under the hood.
