Intermittent bogging while driving...

Have an issue that has me stumped. 91 TBI 350 with 240k miles. Truck starts up, runs, and drives great. No rough idle, no bogging off the line, but once I am moving and hit the gas to accelerate and pass someone or speed up the engine will bog down and backfire. If I let off the gas then slowly...

New guy here figured I'd introduce myself, my name's Tim. Inherited a 91 ECSB after my stepdads father passed away a couple years ago. Had about 234k miles on it and it's pretty rough visually. I've been fixing things and getting it into better shape. Had the 700R4 rebuilt last year in January...
