Did you observe the fuel pressure as the problem was occurring? What was the lowest pressure reading?

The question was, did you observe this while the problem was occurring, meaning while driving down the road? The pressure reading doesn't mean anything if it was taken while the symptom wasn't present.

I didn't think so. That is what needs to be done though. We usually feed the hose under the back of the hood and tape the gauge to the windshield. Make sure you stick a small block or something next to the hose so the hood doesn't pinch it.

OK, that allows us to eliminate fuel supply. at this point you're going to need to use a scan tool to analyze the sensor data to try to get a picture of what is taking place when this happens. You need to see if it's going rich or going lean and see if there is a sensor triggering it.

You're talking about a $5000 tool. You're going to have to pay someone to diagnose it for you.
