We have a hibiscus in a self watering pot that is suddenly giving up the
ghost for no discernible reason. it has gone incredible droopy with many
of the leaves withering up.

You have given the reason. Tropical hibiscus need soil that drains
well. Your pot is keeping the soil soggy and killing the plant.

it was not short of water at any point. i have examined the roots and they
seem alright, although in one or two places it might be the sheathing has
been nibbled or that it might have been some damage in getting the roots
out.

Adding some humidity helps in a dry house. Misting occasionally, some
nearby water, etc.
