My tree has lost most of its leaves and smells rancid and oozing stuff at base of trunk. It is turning black. At first I thought a fox had been around but now think it is the tree itself.

If it is soft, this indicates that rot has gotten into the stem. This is often caused by standing water or too much water. It may also be cold damage. Have you had a bad winter where you are? If it smells fishy, it may be bacterial soft rot. Unfortunately, there is no cure for soft rot.
