You didn’t say anything about an amplifier. Or what a site like antennaweb.org says. Maybe if you indicate your zipcode someone from that area might have answers.

Signal strength doesn’t say anything about signal quality. It’s signal quality that is important

Make sure coax cables are in good shape as well as connectors. I think RG-11 coax cable will provide the best quality for HD over antenna. If I am wrong, I’m sure I will be corrected in comments.
I started losing my local CBS signal but all other stations were ok. I ended up replacing just the 3 ft cable from my wall plate to my Tablo and it fixed my CBS signal and got me about 60 more channels.

In general RG-11 is fine but always be skeptical when someone says an antenna or a cable is “HD” compatible, best for “HD”, or “digital”. The radio signals don’t care about any of that. What you want is a 75 ohm cable with the correct connectors for over the air TV. Things like extra shielding are good for longer cable runs. Just try not to get scammed with all those meaningless “marketing words”. There is no difference between the coax made before digital television and the coax made after.

All that said I agree this sounds like a connection issue or an amplifier issue. A break in the coax could cause the the issue. I would do my best to examine the coax and the connectors. I have heard one person say the antenna connection inside their Tablo got damaged but that’s unlikely to happen unless your Tablo was treated roughly.
