Entire car loses power when we floor the gas. Gauges reset until we let off gas. (still drives)

02 ford mustang. The car loses power to everything. (Except what's needed for the vehichle to stay running.) Can still drive it. What are possible problems? (AC does not affect anything )

Clean and tighten the battery cables and posts. If you have a bad motor mount the motor may be shifting and breaking contact with the cables.
