OK, here are a couple of things you can try to do if you get a chance. I'm not saying what other posters have is wrong but just trying to give a different perspective.
1. People have been debating wheter or not the cables from the splitter to your TVs might be bad. If you think this is possible try connecting your receiver directly to this splitter with a small TV and see if the problem reoccurs. If you still have the symptoms then the problem is further back (satellite, LNB, cabling to the dish). If you don't have the symptoms then it is definitely the wiring between your splitter and your TV.
2. Do you receive the Pats game via your local channels? If you end up needing to wait until Monday to have someone come out, you could connect a small antenna or rabbit ears to your receiver and be able to watch it that way. You would just need to run the setup to have the dish pick up those channels
Just my two cents. Good luck
