2009 Peugeot 207

Engine Mechanical problem
2009 Peugeot 207 4 cyl Front Wheel Drive Manual 1700Km miles

My brother-in-laws manual Peugeot 207 runs on GPL (gas). The problem is that the engine inexplicably (and suddenly) stops. I have not been able to reproduce the problem, although it happens at low speeds (ie turning a corner or waiting at the lights) it doesn't stall, cough or splatter- the engine just dies. It is no problem to restart it. No sure if it is of any significance but the days have been high 20s to mid 30sC and I think the aircon may have been on. The problem is serious enough to be of concern especially if the car is in the hands of inexperienced younger driver (niece). The service dept (twice) have not been able to find the fault or give possibilities or suggestions= very dissapointed.
Your suggestions and advice is welcomed and appreciated.

Check/clean or replace the CKP (crankshaft position) sensor
