2011 Mini Cooper S just shuts off
I have a 2011 Mini Cooper S that I took to the shop for starting and they
dying. They said it was a bad throttle. Replaced that and then it will run for
15 to 30 minutes and just shut off like somebody pressed the off button. Let
it sit for 20 minutes and it will start right up but then shut off after 15 to 30
minutes. They tried everything (sensors, etc) and get to code or anything. It
only has 71,000 miles on it. Any ideas as it is a big paperweight at this point.
