02 Grand Am Ck engine light

02 Grand Am, 2.3 4cyc.,40,000miles it seems that recently when the gas tank gets to 1/4 tank the check engine light comes on. After filling and properly replacing the gas cap and driving a few miles it goes off and stays off. It comes on again when the tank goes low. Do the caps go bad? The cap appears ok. Anyone have this problem?
