My Suburban all of the sudden starting running very rough. I got it home and put it in park and the roughness went away. I revved the engine while it was in park and it seemed normal. As soon as I put it back in gear it starting running rough again and seems lose about half it's power when I try to accelerarte while it is in gear. Anybody have any ideas?

I have a 93 that overnight started running rough while driving and had a hard time going up hills but standing still it was fine. I replaced the fuel filter and everything went back to normal...runs great.
Good Luck
