Is the gas gauge linked to the computer? on 2004 Chevrolet Malibu

Every time I fill the gas tank, the gauge shows full, but after a few minutes the needle falls to empty and I hear the warning indicator that the tank is empty (even though it isn't).

gm's have a high fuel tank sending unit failure problem.have codes scanned and see if you get a code for the sending unit.some of these are covered under gm's cust assisstance program. call the dealer with your vin number and see if your car falls into that.
