stalls wont restart for 5 minutes then runs fine happens intermetantly on 2006 Mercedes-Benz CLS55 AMG

4 times code says vapor leak

Having the same issue. Will rive fine for several miles - sometimes 100s, then unannounced sputter a bit and die. No check engine light, no warning. then it won't start until it cools down for about 5 minutes, then starts and runs just fine. Just had the CPS (Crank Position Sensor) replace by mechanic. Didn't solve the issue. Usually happens on hotter days... Taking it in again for further diagnosis
