At 150 grams those snakes are voracious if I had to guess husbandry is your issue,I wish you would have address the issue a bit sooner, 8 weeks with no food for an animal that size is not ideal it easily becomes a vicious circle of the less food they eat the less they want to eat.
Do this to a T https://ball-pythons.net/forums/show...-hatchling-101 and adjust the prey size to adult mouse.
