Thanks, John. There were two weird items in the modem log- the timing on them was strange... January 1 1970! They did not correlate in the log to the correct times the reboots happened but considering the time weirdness maybe that is not surprising.

It's a common default time. In your case it only tells you how long it has been since the device booted up.
The modem was rebooting every 15 seconds?
