Setup looks good (meaning it’s close enough to handle OK and any minor tweaks that might make better specific to your build or driving style w/o being in person would be impossible to give).
On to your issue - if the kart exhibits the same push at center approximately mid race every time you run or at least every time at this particular track, I would reduce 1/4 negative camber on right front (-2.5 vs -2.75) at that track. If pushing at entry or exit instead, I would add 1/4 positive camber to left front (+0.5 vs 0.25). Anything more than these adjustments will just cause other issues to chase and won’t solve your problem at hand.
I expect, however, the greatest contributor to your push as race goes on is solely due to tires getting too hot from being too soft. The most common cause is being too soft for the track conditions. Why? It’s logical that when tires are too soft, the rear tires having a greater contact area with the track will cause the front to loose traction and there’s your push. Just consider when a rain comes or track is rewatered during race day what happens when you soften tires to make enough grip. You typically also have to move weight from left to right to keep from pushing (and/or a 4 wheel slide if really slick).
A few other reasons for tires going away during race due to getting too hot include: too much internal (could be part of your issue in this case as a 100cc Maxxis seems high for summer in the South), too much air in all tires (more air causes heat to happen faster), too little right/left air pressure split (less right/left air pressure split causes heat to increase on the right sides faster).
I do not suggest you start making big changes to setup to chase a small issue like this, especially if just happened this one time. Tires is where your problem is and will be one of the possible issues stated above. Not being at the track to know for sure, I can only make suggestions based on 45 years of experience. My suggestion would be to run a 75cc tire instead of the 105cc you ran with the push issue and also open the air pressure split to 1 lb for the race (leave at 1/2 lb for qualifying). Good luck!
