Now that you mentioned it, I can't say it died. Don't recall the dash lights coming on. Just pulled over and shut it down then restarted.

I didn't just purchase the vehicle true but I just moved from Colorado where the air density is significantly less than sea level. Was only getting 5 lbs boost in CO. I'm thinking this could be a factor why it's occurring now if it is the same issue. Do you still have your receipt from Nissan, as it should list the error code you had when yours failed. Would like to make sure either way, as I'm getting no help from the dealer.
