Frost damage, wind damage, phytophthora root rot, bacterial blast, and several other diseases can all cause specific branches on a citrus tree to die and lose their leaves. Please see these articles for more information and links:

Diseases vary by region, so you might want to consult a local extension agent or other expert.
