My thoughts exactly. Sounds like it can't pull fuel quick enough, then recovers after a while of not-flat-out. Also check fuel cap- they can collect a lot of crud in them, and become (almost) airtight.

Best way to find out take it for thrash, when it starts losing power pull over and open the fuel cap. If you hear a sudden whoosh of vacuum, there's your problem.

And when there is no woosh. I suspect the fuel tap. The vac operated is a pita. Wil be replaced soon for a non vac operated over here. Waiting for the postman.

Standard fuel tap is fine if overhauled and working how intended.
My N1 has been flat out on the dyno and no issue with starvation at all.
