Hi again:
Something is causing it to shut down, but without the check engine light, it makes it more difficult. If I had to guess, I would say MAP sensor, but without a code, again that is a guess. IF you are sure the fuel pressure is good, here is what needs to be done. The vehicle will need to be checked with an onboard diagnostic scanner while it is being driven and acting up. THe scanner should identify what is causing the problem. I recommend this because there is such a long list of items that can cause this to happen. If you start replacing parts, you could have hundreds of dollars into parts that are not needed.
I wish I had an easier answer for you, but this is the reality of it.
Please let me know if you have other questions, or need any information, and thanks for using 2carpros. Com.
