Intermitant stalling, would restart after a few minutes.Seemed to be getting progressivly worse with warm weather. Following suggestions in this resource, and position sensor code PO336, changed out sensor. Been driving a week now and no further problems. Thanks to all for their contributions.John R.

my car will turn off after about 10 minutes of driving, it will start back up after i let it sit for about 4-6 minutes
04 MC SS died while idling at a stop light and would not re-start. Came out of the blue - didn't have any issues with the vehicle beforehand. Had the vehicle towed and the MAF sensor (battery as well) replaced. Ran fine afterward.
MAF sensor failed at 140K miles. Was constantly stalling for about 10 miles then just refused to start up again.
