Front squats EMOTM, getting real up in here!!!
You may be able to recover some of that strength and energy for your sessions by having 1 big protein and carb heavy meal the night before after a 24 hour fast compared to the 36 hour fast then trying to carb up before your sessions. You could also be experiencing leverage differences from the weight loss. You are going to suffer from worse leverage points the smaller you make yourself. So even if muscle strength has not gone down the muscles have to apply more force to move the same weight due to worse leverage.
