O.k.,this can be a difficult one to answer from here with all of the components that can fail or act up and cause this issue.It is possible this is the injection pump supplying low fuel rail pressure intermittently as this can be common.I have also seen issues with the electronic ignition switch in some cases not sending all the signals needed intermittently needing replaced.But there is a large number of different components that can cause this and these are common components listed here.

The best thing to do as I have had to do myself before with my customers is to see if the dealer will take and hold onto your vehicle for a few days or more so they can duplicate the fault.Then once duplicated then they can test/diagnose the issue to help locate which component is at fault needing replaced.I have had to ask my customers in the past before with faults like this here if this is an option,this way I could operate it and duplicate the issue with my test equipment connected to locate the fault.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service,your 5 star rating is appreciated.You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.

Thanks Pete

Call me little disappointed in the answer it's typically dealers and friends mechanics basically say the same thing but nobody can find it so I'd like to have the $23 back thank you
