Green Lantern, Vol. 2

Hal gets an upgraded ring from the Guardians before heading back to Earth to check on Ollie. The pair soon encounter a spacecraft buried in the sand, and help an alien being pursued from it. Hal takes the alien off planet, while Ollie stays behind. The pair soon learn that they've helped the wrong side, as the troubled alien takes Hal's power battery and leaves Hal tied with yellow rope in a yellow cave with barely enough ring power to keep breathing for another 40 minutes.
