Hello, Welcome to Just Answer,

This is a very hard thing to say just what the fault is. There are a few possibilities that can cause this behavior.

1. Ignition switch

2. fuel filter

3.Crank shaft sensor

4. Immobilizor

5.Battery

Vacuum pipes/ or a bad intake manifold gasket or intake pipe

The way to really tell is to get the fault code. I do have to menssion that at times the fault code will not reveal some of the problems as these kind of faults does not trigger a fault code. The vacuum pipes, fuel filter and cranks shaft sensor are the ones not always causing a fault code. The crank shaft sensor operates in a very hot area causing the wiring spool inside the sensor to get deformed and then the sensor is sending a weak signal to the ECU causing the ECU to cut the engine to protect it.

I do hope you find this information of assistance should you need more please do not hessistate to ask.

Greetings,

Martin.
