Tree Appears To Be Dying

Question

I have a maple tree that has suddenly developed yellowing leaves and the leaves are falling almost like it was fall. I have noticed several trees in the neighborhood that have done the same thing and have died. They are all types of trees, from Bradford pears to evergreen varieties. It seems just one tree dies and the neighboring ones are unaffected.
