Internet disconnects same exact minute, most every hour, last 2+ weeks

I'm getting disconnects most every hour at the same exact minute, we have had the same setup here for years and never had this many constant disconnects.

Last few days the phone reps have just told to power/reset modem a total of 5 times or better. Yesterday I was told on the phone there was an outage that would be resolved at 10:56pm, but it didn't. Tried calling today and customer service phones were totally down for a while, once back up I got the robot to ask me to do another reset, no help.

When it goes out, no lights on the modem go out, and it's back up and going in 30-90 seconds. After I noticed it was the exact same minute every day, just recently I made a log of when I was using my computer and it disconnected:

5/26 7:06pm, 11:06pm

5/27 7:36pm, 11:36pm

5/28 7:36pm, 11:36pm

5/29 7:36pm, 11:36pm, 12:36am

5/30 9:36pm, 11:36pm

5/31 11:10pm, 1:10am

6/01 8:28pm, 10:28pm, 11:28pm, 12:28am, 1:28am
