Could be alot of different things. Have you kept on maintenace? A problem like this I would recomemend the usual oil filter plugs wires. Check them out make sure they are all up to date with your schedule. A similar problem like this had come up and the kid took his car to Honda which in turn they said to flush the tranny it may be dirty. I think it might be the cat but you would see a code being thrown.
