I would like you to peruse the options in this link. You are on site and I am not so I could only guess. See if anything matches what you are seeing. if it were Emerald Ash Borer, there would be D shaped exit holes on the tree. I will give you a link to that too even though you do not see any insects. http://apps.extension.umn.edu/garden/diagnose/plant/deciduous/ash/leavesbrown.html https://extension.umn.edu/tree-and-shrub-insects/emerald-ash-borers
