I have a problem with my headlights cutting off at night. ALL lights go out, headlights, parking/tail and dash. If I turn the switch on and off a few times or wait about 30 seconds with the switch off, the lights come back on but will go back out in less than 5 minutes. I should also mention (might help) that, when the lights cut out, the dome will not work when I push the switch in. I'd like to know if there is a likely cause so I can have it fixed. Thanks for any help.

I saw your post and I too was having this problem but only with my low beams, everything else is still fine. You could have a few problems, so heres what they could be:
-1. CVPI's from 2000-2005 have been known to have bad LCMs(lighting control module). To replace it is easy and can be done yourself. It is located under the dash to the right of the steering column. Looks like a black box with 3 wire connectors on the back, 2 gray, one black/white. Cost is around 400-450 depending on dealer. Recommend to buy new, not used, though can find used for a lot cheaper but no guarantees of future problems with used.
-2. Bad Multifunction switch in steering column. Requires replacing whole turn signal unit. Easy to do and does not require a mechanic. Cost is about 70-100 depending on dealer.
-3. High beam flasher may still be installed from police use. Remove and install proper wire loop for high beam operation. Located either on the radiator cross beam under your hood or above the front right wheel well.
-4. Bad or improper fuses. Check your fuses and relays under your dash. If they are not the correct amp fuses then it will cause problems. If they are blown you should replace them.
-5. Shorted dome light wire. Some CVPIs have their dome lights unhooked for stealth mode operations. Check above your headliner to find dome light wire and if it is disconnected then check for possible grounding. If it is shorted then you may need a vehicle electrician or mechanic to replace wiring and check your ECM for faults.

If it is none of those then I hate to say it but you may need to lay down a lot of money depending on who you take it to. Hopefully it is one of the first three I listed, they are not too hard to fix and you won't spend too much to get it fixed. I know what you're going through, I just got mine fixed after spending a lot of time and money and learned a lot in the process. Good luck to you!
