How is it that Haval h5 gasoline 2.0t will turn off after starting the car all night?

The common causes of auto-flameout are: (1) vacuum leakage of intake pipe; (2) Idle speed instability caused by improper idle speed adjustment, dirty throttle body and poor idle speed control system; (3) The fuel pressure is unstable, such as excessive wear or poor contact of the electric fuel pump brush, or the fuel pump filter screen is blocked; (4)EGR valve is blocked or the bottom leaks; (5) Fuel pump relay, EFI relay, ignition relay, etc. For example, the high-voltage spark is weak, the spark plug is used for a long time, the ignition timing is incorrect, the ignition wire coil is poorly contacted or there is a turn-to-turn short circuit in hot state, resulting in no high-voltage spark or weak high-voltage spark, poor contact of low-voltage lines, intermittent grounding and poor grounding due to damage of insulating glue, etc.
