That sounds like a pretty aggressive feeding schedule, i wouldn't be surprised if he just wasn't hungry.
Also, depending on where you are located, he could be getting ready for the breeding season, as he is getting closer to sexual maturity, and has other things on his mind than food lol.
10 days is a blink of an eye in the snake world. As long as he isn't losing weight then you don't have to worry too much if he refuses to eat. It doesn't sound like he is dying
I would switch your feeding schedule to every 7-10 days anyways, and reevaluate the size of the prey you are feeding. Prey should be about as big around as the snake, at his widest point. He will likely calm down after breeding season has passed, or maybe was just having an off day.
Double check your temps, and offer him food again in a week.
Best of luck.
