Thanks Matt - I'll have to trace all the ground wires coming off the battery and see what they look like at the ends. The battery terminals/connectors are clean now as is the main ground coming off the battery going to the body. I actually sanded away the paint on the body, then re-attached the ground.

So far,the problem hasn't come back, but that doesn't really mean anything, since I really haven't found a root cause.
