Glad you were able to get your problem resolved. The shut off problem I discovered quite by accident while jumping on the freeway. Had that happen twice, since I had the check engine light on I figured they were related. I'm thinking the ECM is seeing a dangerous situation when in the high RPM and as a precaution is shutting the motor off. Not sure what it could be but makes sense in the long run, especially when you are talking the RPM being up that high.

When I first posted this you can see I got a whole lot of feedback. I was rather disappointed too because it seems like on other issues in these forums you get a huge response back. I guess this was too much of a challenge to the tech types out there. Regardless I figure if I am able to help even one other person out there it's worth it. Glad I can be of assistance.
