I've noticed my '97 Tahoe doing something similar. Around town speeds it's never noticeable. It's only when I get up to steady highway speeds. It's also random with mine. Some days it does it, & others it does just fine. I've also been on longer road trips where it would start doing it & eventually go away. Sometimes it would come back later on, but other times it never did it again. I have no clue why it does it. I haven't tried to dig into it much. I tried the fuel filter with no change. In late 2016 the distributor was replaced, & shortly thereafter the fuel pump & sending unit were also replaced. The miss wasn't there before that work was done.
