Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.

The first thing that needs done here if this hasnt been done already is to have the fault codes read out/checked to see what codes are set.Once this has been done any codes set will need diagnosed to help locate the fault here.

Does it feel like the engine is shutting off real quick when this occurs then coming back to life or does this feel more like an engine misfire causing this fault here?

Let me know so we can continue,thanks Pete.
