Frequent short service interruptions

For about 1 week I have been experiencing numerous internet outages, each lasting 2-10 minutes. All devices and all access to the internet is lost (TV streaming for all services, email, web searches, gaming, etc. Devices affected  include WiFi and ethernet connected. When down the modem status light is blinking yellow or green. (When up, steady white). I have already called, and an agent reset some things remotely on my modem, but that has not fixed the issue. I have done several speed checks during "outages" and they all come back OK (although, not 100% sure modem was down during checks because of the short time of down periods). Mostly this happens 12 - 5 P, but today I had outages at: 11:40A, 1:10P, 2:28, 2:35, and 2 more between 4-6P. Between outages, service is perfect on all devices. This is becoming very annoying. Are you guys working on your cables to my area, maintenance,  or some such? The map shows no outages in my area. Thanks for your attention to this.
