The problem of not eating gas?

I'm using 1.4hdi 307, friends .. While on the long road, the car suddenly stops eating gas and the fault light is on. I slow down and stop and run again until the cycle is minimized. I stop and restart the vehicle in motion on the move.

There may be different reasons. When the malfunction light turns on, you have to connect it to the computer and look at it.

The vehicle error code has dropped.
