ML320 runs fine then stalls
 

My2001 ML320 runs fine but when I drive for about 15 to 20 minutes it stalls and won't start back up. After about 45 to 60 minutes it starts right up again and the same thing happens does anyone know what my problem might be?

There is a rpm sensor in the back of the motor on the transmisson housing. I had the same problem on my 500 sl and that was the problem.
