Hi Patrick -
Regarding the deformity of the new leaves, I suspect the persimmon psyllid. Do you have a microscope or know someone who does? Identifying whether an insect is causing the leaf curl would be helpful.Persimmon psyllid can contribute to fruit drop.
Also -
Do you have a male tree nearby for pollination? Lack of pollination certainly can cause to fruit drop.
I would also prune the tree to allow more sun and light into the center, and start training it into a properly structured orchard tree. I'd also thin the fruit so that you have the correct ratio of fruit to branch for the size of your tree. Thinning the fruit will help the tree retain what's left and will also make the yield from year to year more consistent.
I'd also suggest considering whether you may be over- or under-watering the tree.
Good luck and hope you get some persimmons soon!
