You may have a bad cat. converter. Have it checked before replacing.

Check engine light on??? Manually put it in low gear before you start out and see if that helps. Possible trans. not downshifting properly. (If auto. trans) if it were the cat. it would not recover at any speed! You say it is ok once you get up to speed, so i'm thinking trans. shift trouble. Also light should be on if exhaust is restricted that bad. Let us know how it turns out.
