Chevelle lost all power while driving, later regained power after sitting.

A friend of mine had a Camaro that used to do this. He took it to many different garages with no avail. I read up on it and told him it might be his coil. When it heats up the coil screws up inside. We were out together and it happened. We got a cup of cold water and poured it on the coil and the car started right up. He replaced the coil and never had any more problems.
