It could be too much water, but what I'm wondering is... What is the soil type? It could be way too alkaline if there is a lot of limestone around. Second suspect would be fungal. Either way, both can be corrected with Wettable sulfur. Spread this according to the packaging instruction and it will stop the spread. What is dead, is dead, and will be replaced on the top and tips of the branches.
