if you somehow end up in a position of 0hp but have temp hp, do you fall unconscious? Has this come up before?Please explain how you got into that situation.

Strength Before Death + Fighting Spirit. Strength Before Death says you fall unconscious if you have 0 hp when it ends & the rule on temp hp in the PH says what happens with 0 hp.
