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.

One very common component that causes this issue here that I have had to replace several times before is the crank position sensor itself.This sensor will fail to send a signal to the engine computer on the crank shaft position.This is most common after the engine has ran a bit or coming to a stop.When it acts up the vehicle usually has to sit anywhere from 1 minute to 10 minutes or more before it will restart and run.In allot of cases this sensor when it acts up will not cause a fault code to set making it difficult to diagnose.

With what you have described here this sounds like the component at fault on your model here needing replaced.This sensor is located behind the crank pulley/harmonic balancer and can take around an hour to replace.The part itself is usually less then $100 and can be purchased at a dealer or parts store.This does require a special puller to remove the crank pulley/harmonic balancer to replace it.

Are there any fault codes setting with this issue here at all?

Have you tested fuel pressure and spark when it will not start to see if these are present?

Let me know so we can continue,thanks Pete.
