You know what? My 2008 Town and Country is doing the same thing, but the lights go out after driving it a little bit and doesn't happen all the time. I'm just chalking it up to 120k miles on it and a bad brake job done by an idiot. It's my company car so I don't really care, but I'll be doing the brake job myself next. Then I'll see if everything starts working again.
BTW, did you recently have your brakes done? That is when my van started acting up.
