Whe the problem happens, check the vehicle's fuel pressure to the engine. You may have a weak pump. Also, check to make sure you are getting a good hot blue snapping spark to the plugs.

I do not believe this to be a spark problem. I replace the weak battery, the primary coil, the fuel filter and EGR vacuum valve. A mechanic thought it to be either a fuel pump or electrical connection to the pump.
I have had this problem for over 6 weeks with it rarely occuring to now happening ever time.

I am questioning it be be the fuel regulator valve or the pump. I do not have a way to test the pressure. What should I do??

You need to check fuel pump pressure. Most parts stores will lend you a gauge. There are detailed directions and a video on our home page under the DIY section for doing it. Check it out and let me know.
