I'm having issues with my 2006 RR. For the past month my RR stalls/shuts down (but lights, radio still on) while I'm driving or when it's idling. For the past week or so it's got worse. After it sits for 3-10 minutes it starts back up. I've been researching this and all I can come up with is the crankshaft sensor or fuel pump is bad? If it was the fuel pump wouldn't it just go out and not start back up at all?
