See if you can can any stored or pending codes read for a starting point. It could be one of many things such as a faulty crank sensor.

I did send the car few times to bmw. But on the computer is not showing any faults at all. Anyway thanks Brian

Won't always show codes on intermittent problems. I'd suggest if it's not a major pita to pull the crank sensor and do an ohm test. They should have different values resistance for a working and non-functioning one. You could warm the sensor up with a hair drier and simulate what the ohm reading is warm and compare. Many dealerships just replace parts and refuse or don't know how to properly test parts. Obviously intermittent problems are the worst. The only other idea is that perhaps you lost heat shielding near or around your fuel lines. Usually on most newer cars vapor lock is not an issue but anything goes. Good Luck will check back on progress.
