We have a 25-year-old Wisteria vine that has not bloomed for the last two years. It also has shown signs of dying and drying out. I consistently water. We live in Arizona at 5, 000 feet, so we do not get the intense heat that the Valley gets. I'm just wondering if they finally just die out of old age, and is my best choice to just cut it down?

Yes, it could just be dying from old age. Individual wisteria vines normally last 10-20 years, but are normally overtaken by younger vines, so people do not notice when older vines die back.
