2003 Grand Am - Loss of Power

I was driving and came to a stop. I started going again to only have the car stop moving. All the power was still on in the car, however I could not get the car to move. When I stepped on the gas pedal the engine reved, but would not go. I turned the car off, and back on after about a minute and power was restored. Anyone else have similar problems?

Sounds like it's a transmission issue. Check the fluid level and condition. If both are good, you may need a re-build.
