Hello and welcome to JustAnswer!
There are many things that an cause the symptoms you're describing, it's going to take some electrical testing at the time the problem is happening to determine exactly what is going on.

You seem to be describing either an internal failure in the instrument cluster or a loss of bus communication. The modules all communicate over a wired network. If the instrument cluster loses communication then it will cause what you're describing. If the bus goes down it could be a wiring problem or a failure in any module shorting the bus to power or ground.
