My GT had this problem as well. It stems from the headlight switch, because of the fog lights. Running the fog lights creates a high amount of current, and consequently resistance, running through the multi-switch, causing it to overheat. A thermal deactivation switch built into the headlight switch causes everything to shut off for a few seconds, and go back on.
Perform this procedure. I did it to both my old GT's and had no problem since.

Replaced the switch and stopped using the fog lights, and they stopped getting hot. I'm definitely going to do that fix so I can use the fogs when I get time.

Update- Talked to a guy at carquest and he put the idea in my head that it might be the fact that the starter is getting too hot... With the shorties running up front, and then the exhaust coming off the turbo and going right by the starter I think that could be the problem. Anyone know where I could get an aftermarket heat shield for the starter? And the headlights are working reliably now, but the dash lights are acting funky. They work at random, i'm hoping replacing the starter switch and the multifunction switch will help with that.
