A similar thing happened to me, I filled in fuel from another country (different from my type of fuel) the engine light came on, after that, the RPM drops when filling the fuel, and after that the car turned off after filling up for some time and I changed the sensor and it did not turn off after filling up but when stopping and filling it still is The RPM drops. now the car is turning off with frequent stops!! (after years xD). The mechanic suggested that I change the petrol pump and some of the sensors, and clean the injectors, throttle, etc... i still waiting to receive my car and i will up
