yeah, that can happen easily with the way some are plumbed, and usually are heat and distance run related. If the pressure is moving around at all, like the pump is cavitating from the fuel heating up in the tank, it's an immediate hiccup with efi. It's just part of the tuning process, and you need to be able to verify the basics at the time a problem occurs. Datalogging is great, but if the fuel pressure is moving it throws a wrench in the works.
When this was happening was the a/f moving around at all? Did you notice that the fuel pump was louder?
