Wanted to give everyone an update.
I put the computer on another circuit and the router and dust collection run off their own circuit. Since I did that I have not had any issues, even with more complex carves such as 30x30 carves into 1/4” plywood. Computer has not quit on me once over 3 full days of carving.
That leads me to think that the noise generated by either the vacuum or the router causes an interference somewhere that the computer or network doesn’t like.
Thank you very much for everyone’s input. It been driving me nuts, and I can finally sleep again.
