Have you checked if it is losing spark when it dies? If it doesn't start right back up, have you rechecked fuel pressure at that point? Have you checked to make sure the injectors are getting power?

It could be several things. I will assume that you checked the crank sensor. Have you checked for trouble codes?

I wish I could, but we are not allowed to give out that type of info. I will be on line. You can get me this way.

You asked about other problems, the ignition module could be cutting out on you.
