Show freezes, goes black then resumes

I have 4 cable boxes. 3 satalite boxes that connect to our X1. For the past few months we’ve been dealing with the viewing freezing for freezes for 5-10 seconds. Goes black. Then will resume. It does not pick up with when it froze so you miss what may of occurred. Yes I have checked all my connectors. Also have had two techs out who have ran tests and have found nothing. This happens daily. Doesn’t matter the time of the day. My neighbor deals with it as well. No we are not in a storm area. There is no storms going on during it. This is getting to the point where the techs over the phone do not seem to believe me that I’m about to just cancel and go with someone else. Is there anyone else that has dealt with this?
