The most common problem with these vehicles is a fuel pump starting to go out and starving the engine for gas. It will get worse as time goes on.
It could be the electrical ignition system. there is a recall, dealers will replace the ignition relay free of charge. check it out. Pontiac tele. #1-800-620-7668
sounds like an ignition coil
did you have your ignition coil replaced? the signs are that the ignition coil is overheating thus you are able to restart after an hour, when the coil cools. also check if your ignition coil has a resistor. if it has, have it checked for continuity. did you have your ignition coil replaced? the signs are that the ignition coil is overheating thus you are able to restart after an hour, when the coil cools. also check if your ignition coil has a resistor. if it has, have it checked for continuity.
It has a 2.2L and i have replaced fuel pressure regulator plugs map sensor and to other sensors on the throttle body. Driving habits may be an issue.

Bad ignition switch or starter solenoid
I had this camaro sent to a Chevy dealer to be repaird. They said they replaced the ignition switch. I found out that they replaced the ORANGE wire coming from the ignition to the CCM. That's the orange wire that has 2 wires inside the 1 orange wire.
The antifreeze level could be low, or the thermostat may need to be replaced, or the antifreeze line might need to be blead to get all the air out, the air in the line will make it overheat.
the voltage regulator
i bet it wouldn't be hard to put the headlights on the radeo power that comes on when the ignition is on...
