Kousa dogwood dying

What is causing the end branches of our 4-yr. old 8′ Kousa dogwood to die? There is a hole bored in the center of the branch when we cut the dying part. We have applied Systemic granules today. The tree looks very healthy except now seeing the end branches dying. Can we save this very special tree that just began to show blooms this past spring?
