Q.My Healthy Virburnum Hedge Is Suddenly Dying At The Top, Please See Pictures
I have very healthy viburnum hedging which is very healthy and growing great at the moment. In a small section, about 3 ft in width, the top leaves have all died off. Not sure yet if it is spreading as I have just found it. I have attached a picture of the damage and some leeaves.

This is, almost certainly, a root rot issue. Whether bacterial or fungal, you have a really big issue on your hands.
Check for mushroom fruiting bodies at the base of the shrub. Check for oozing lesions anywhere on the shrub.
fungicides may slow the progression, but this is likely a disease that will require replacing the shrub with something unrelated.
