Chevrolet S-10 Catalytic converter Problem

My s10 4.3 runs very good until 2500 to 3000rpm then sputters and jolts hard when accelerating, wouldnt know there was a problem without punching the gas

Check fuel pump pressure to make sure it is within spec. Also, check the catalytic converter to make sure it isn't plugging.
