Might run the rest of day or like yesterday mess up again in a few min. Just repaced the fuel filter and i checked my fuel pressure when it was running good and i had 39 pounds. Im going to take fuel pump out of tank and see if it has a sock filter on it. Please let me know if you fix your problem

exactly what mine was doing last year-- had to replace the fuel pump (fuel tank and all).

Similar to a recent post......I'd check the throttle body for grime build up.....Pull the rubber boot to the TB and look into the TB for buildup....Open and close the butterfly and clean the TB and the butterfly with 3M Throttle Plate cleaner with a Q tip.....Let us know....

I had a similar problem with me race car ..... after weeks of trouble and expense I found the problem was in the tank at the fuel pickup. There was crap in the tank and after the car would round for 5 or 10 minutes enough crap would get on the pickups screen to nearly stop the flow. Shut it off and move it around all the crap would drop off, then start it an same thing would happen. Also the filters on EFI are very fine, not sure on the microns but I also had an issue with Top End Lube we were adding to the Methanol to take the edge off was thick enough even with low concentration that it would clog the fine filters just before the injectors.
