Since you are willing to have an arborist come take a look, go ahead and do that. When it comes to trees, it is very difficult to diagnose issues without being on site. With such a mature tree, it is not likely to be a water issue. An arborist will check for signs of disease improper pruning cuts, and cultural factors that may be impacting fruit production. Good luck!
