bogging at 50mph - The 1947 - Present Chevrolet & GMC Truck Message Board Network

this is a odd symptom that happened last week and i have no clue what it could be.

69 c10 2wd
230 inline6

truck starts perfectly, idles perfectly and runs perfectly, up until 50mph. once i pass 50, the truck jerks almost like a fuel problem. jerks back and forth hard. if i take my foot off of the gas immediately, i can keep it running once the speed drops. if i keep the gas steady it will die, but starts up right away and idles again perfectly. below 50, i can floor the pedal without any bogging.

i noticed a torn up alternator belt, so i replaced that. did not fix the issue.

i am clueless. any ideas?
