If you go into the options and change the threshold for auto-pausing, maybe that would help (though if the game checks the hitpoints only when you take damage and you are getting one hit killed it wouldn't make a difference).
If you turn the sound off and keep reloading you should be able to eventually pause when Stone misses. Level 1 of the Evade skill comes in handy (10% chance of avoiding melee attacks), more so early in the game, though it is a little late for that now.
There may be a trainer you could use to enable unlimited health, or something, until you get through that fight.
