Even dark souls allows you to regain stamina. There ought to be a way to regain your stamina that doesn't require you to chug potions/eat herbs & food as if it was Skyrim.Yes? Don't let your stamina run out, use potions or herbs if necessary.
It should probably just leave you vulnerable for a while instead of indefinitely, and as for the capturing sequence when you run out of stamina and "rest" to the next day/night, in where you get captured. Have HP handle that for you where the ones that kill you. kill you. And the ones that capture you. Capture you.
