FED 87 hit the nail on the head! I had the same thing happen this year at Great Bend. Data logger showed no fluctuation in fuel pressure, I pulled the fuel filter to see if that would make a difference. None. My engine builder suggested it was probably the pump. I replaced the pump, and checked calibration of fuel pressure sensor, it was within .5 PSI of a calibrated instrument. Next time out my car was back to normal.

Good luck
