First, change the filter...easy 10 minute job if you don't mind getting a little gasoline on you.
Second, don't let the car get too low. Many modern cars run at higher fuel pressures than cars used to so when the tank is low there is less fuel the pump has to use. Plus, when you accelrate the pump is trying to suck in gas that may have 'slid' away from the pumps pick up so its trying to suck in gas that isn't there. I doubt the pump is a problem but you might check it out if the car does this consistently. The pump is under neath the back seat and I believe you can test it while its still installed in the car. Check a Haynes manual.
