It could be a recurring fungal disease such as a blight that overwinters in dropped leaves. Be sure to clean up any leaf litter during the summer to prevent a carryover of disease. Also, prune it yearly to increase air circulation. Prune out the dead and diseased stems to help stop the spread. You can also try spraying with a copper-based fungicide.
