Hi my name is ***** ***** I will be happy to help with this today.
The most common cause for what you have described here that I have seen several times before on this model with the engine that is in it is the crank position sensor itself.This sensor reads the crank shaft position and sends this signal to the computer and ignition components.Over time and mileage this sensor becomes weak and loses signal intermittently causing either a stall out or no start or both until the vehicle has sat and cooled down a bit anywhere from a few minutes to an hour or more.
This sensor is located on the back of the engine block just above the engine oil pan as seen in the link below.It is held in place with one bolt and one electrical connection plugged into it.If this sensor has not been replaced I suspect it needs replaced due to the symptoms here.Codes can set when the sensor causes an engine stall out as this is a sudden stall out that causes other electronics to set fault codes.In allot of cases this sensor will not set a fault code for itself failing.The sensor itself is usually around or less then $50 at a local parts store.
If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service.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.
Sounds good.Let me know what you come up with on this here when your ready.I suspect the sensor itself is the cause here needing replaced as this is most common.
I apologize for the delay as your response wasn't showing up for me until now.
Was the crank sensor replaced?
Are any codes still setting for this issue here and if so what codes are they?
Did you already replace the oxygen sensor bank 1 sensor 1 yet or check the wiring to it to make sure it is all o.k.?
