Constant Internet outages

The internet in my house has been extremely inconsistent for months now. We've changed modems out 3 times and changed wireless routers out twice. We recently got a gateway modem from Cox hoping it may help the problem, it has not.

The previous modems and now this one all do about the same thing where they will run for an hour or so then suddenly drop internet connection and blink out all the lights except the power, they then turn back on one by one and begin blinking again restarting the one by one lighting up sequence. I've used the reset button on the modem, I've unplugged for a few minutes and plugged back in, and sometimes it works for a few minutes but then repeats going offline and restarting process again.

I've had techs come out to the house twice and the first time he said we were getting a 'nasty signal' so he went to the pole changed same of the wiring from the pole to the house and went back to check that signal again, it must have looked good at that point and he left after making sure my internet was working, it did work for about three hours and then began the same restarting process again.The next time the guy came out i explained the issue and he changed out some of the coax ends and left. not more than 20 minutes after he left the modem began its restarting process again.

I've read some of the other articles here and it seems a number of people are having similar issues, but none of the suggestions they received have seemed to work for me. I'm posting my event log and connection status but i am not sure what they will say if anything since the internet is actually working at this time. Thanks in advance for any advice or help.
