Q: High Speed "surging" or "miss" on 1994 Chevrolet S10 Blazer

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
While holding a steady 65-70+ mph going up steep hills (North Carolina)engine will surge or miss under load (can't tell which). Within last year replaced plugs, wires, ign cap and rotor. Within last five years have replaced in tank fuel pump, cage, external fuel filter, both pressure/return fuel lines and regulator in the intake plennum chamber BTW I just went on a 1k mile trip and got a solid 21+ mpg! No diagnostic codes are displayed.
