I have the same problem with fuel starvation and since the car is setup to run lean, after a good hot run, she just runs out of gas and is pooped. This only happens when I'm running the car 90/90 (90% of power bandwidth, 90% of the time).

Time for a piggy back, bigger injectors, fuel pump and Throttle body.

We think the issue is the tank/pickup, as we only had this problem in Turn 6.

Certainly a new fuel pump, one with a better pickup design could help, if that is in fact the issue.

But putting more demand on the fuel system with some of those other parts could make the issue worse.

Piggy back is in the works. We can not touch the throttle body. And we are looking at fuel cell options.

I don't think we are experiencing the "same" problem. On Saturday this happened well into the race, with two laps to go, and less than a 1/4 tank of fuel. On Sunday I got on lap 3 with half a tank, and then again near the end of the race when the low fuel light was on - but always in the same turn.
