electric problem

We have a 2000 intrigue thats having electric problem once in awhile. The inter dashboard lights goes all out then comes back on after driving a few miles. I have checked all the fuses and found no defected. Still cant figure out whats causing it.

Well that isn't much to go on. If the headlights are fine and just the interior lights are funky then perhaps it could be the dimmer control knob for the interior lights.
