He did not lose it, he sacrificed what he had left of it to repair Mjolnir after his fight with Bor, Dr Strange said it was neccessary to do so in issue Thor #602. Dr. Strange also said that Thor would be at his old power levels before his first got the Odin Force after it was finished. So he didn't lose, just sacrificed it, but none the less he does not possess it anymore.
