runs ok unless 2500 rpms or more on 1994 Nissan Pickup (D21)

I have changed my fuel filter but when I get up to 2500 rpms my trucks starts spitting and sputtering bad and if I try to give it more gas completely loses power ? I was told it was my catylitic converter just wondering is ther anything else I could check other than this?
