Mine was doing this on the rear tank and I think it had something to do with the pumps ability to pull the gas out of the tank. I added a electric pump in line ahead of the pressure pump and the problem went away. I don't think the FI pumps are meant to pull the fuel only push it under pressure. When you get below a half tank the siphon action is not strong enough to keep up with demand. I think this may be part of the reason new cars have them in the tank.
