BP's and other snakes are self-regulators on food intake at some point in their life.
Whether it's at 1 yr, 2 yr, etc. They know when to load up for egg production and shut down in the winter. And sometimes load up before the winter shut down.
Sometimes they just don't need the food and refuse to eat. We humans have a hard time accepting that since we like an eating schedule for ourselves and our pets.
I agree with Ziggy and don't reoffer food until the next scheduled time. And no need to go to live if F/T has been the diet, unless there are issues such as unhealthy weight loss or breaking a never ending hunger strike.
