it sounds like it is coming from the dash board ,it dose not do it every time ..
 
You are sure that it's not the auto-destruct, right? (Just kidding.)

Could it be a loose connector, either electrical (like a wire that runs to some gauge) or mechanical (like a fastener....screw, bolt, something)?
 
is the steering wheel shaking slightly when this happens? if so you probably need your wheels balanced.
