At the same time as posting this initial question, I sent an email to cox support with the same information. This is what they sent back.
Thank you for your recent e-mail to Cox regarding technical support for
High Speed Internet. I understand you are currently experiencing
connectivity difficulties. I am sincerely sorry for this inconvenience.
Allow me to inform you that I checked the modem signal levels, and this
unit is offline; is not receiving or sending any broadcast signal for
the Internet. This can be determine as the main cause for this drop off
issue.
To solve this matter, I can offer you to swap or replace the modem for
any of our DOCSIS 3.0 modem, dual band or gateway; for further reference
you can use this following link:

If you decide to replace it, you will need to contact us back once you
have the new modem for us to register it and assure the signal is being
sent properly.
We hope this sufficiently responds to your inquiry. Thank you again for
contacting us via e-mail. Please let us know if we can be of further
assistance, we are 24/7.
Best regards,

First, I appreciate the response to my email. It was on the same day, as promised. But, I'm not sure that my problem was actually addressed in the response.
In my original post I pointed out that it is highly unlikely to be a modem issue. The response I got suggests the contrary. I just want to take the time to clear any potential confusion in the air...

you say the unit is offline, as in turned off? It has been on all day, but the log is filled with time stamps showing it not being able to receive information, thus causing the reset. Unless one of the intermittent pings caught a time when the connection was dropped I'm not sure how this is a diagnosis or analysis toward a proper solution. According to the modem log it is trying to talk with Cox, but is getting no response during those moments of down time.

I took a look at the reference material that was suggested. It took me to a list of "Cox Preferred Devices". I assume in the response in the email you are saying that the modem I have probably does not meet preferred spec. i.e. DOCSIS 3.0 modem? The modem I have is a a Netgear-CG3000D (Standard Specification Compliant: DOCSIS 3.0). The modem I have is on the Cox Preferred Devices list. Again, please refer to my original post to see that the modem is not the problem.
If anyone has any ideas or actual solutions, please respond to these posts. We've had 8 drops today between the hours of 9am and 3:30pm alone. Please respond.
Thank you.
