duckman, I'm sure you know, but maybe some don't, I'd make sure not to leave the rounds standing on end while they are waiting to be split. They will pull ground water thru the end grain like a sponge. I have some 20" yellow pine rounds that were cut last winter, i'm about ready to split them and see what the moisture meter reads. Like you, sometimes you got to cut, but don't have time to split, these rounds have been kept under a shed, so it'll be interesting to compare against some of the same wood that was spilt. Hell, it's something for an old man to do, pitiful as that might be.

Yeah, it sure has been steamy here lately, low 90s and not much breeze. Probably about the same there. But if a front does come through, I'll get relief before you do. If that sprocket is chewed up enough it will bog the saw down, happened to my neighbor. How easily does the chain pull around the bar by hand (when the saw is off, of course.)
Check the spark arrestor screen inside the muffler. There should be two bolts (allen head if memory serves). Take them out, remove muffler and look at back side for the screen. Clean it up and reinstall - easy fix for a low power. Just in case the sprocket isn't the problem, and cheaper to check!
