i had one experience with fuel starvation this summer. it was at shannonville motor sports park. It was near my 3rd 20 min session. It was between turns 2 and 3. The 2 turns are usually taken together as a single turn at a speed of about 70 or 80 km/h in second gear at about 60 or 70% throttle. Fuel was about quarter of a tank, so 4 dots. As I was between the 2 turns, I lost all drive to the wheels and the engine went down to idle. The car coasted to a stop on the short straight right after turn 3 and the engine just wouldn't rev past idle. I thought it was limp mode but my oil temp was ok. Also limp mode cuts rpm at 5000. Tried shuffling through the gears but the car still wouldn't rev past idle. A couple of cars went right past me at high speed and I was in full panic mode. Eventually after a few seconds I managed to creep onto the grass at the side of the track. After a few seconds of pumping the throttle the engine finally came back to life. Fuel gauge was showing only 2 dots.
Then on that same lap at the hairpin (turn 10) I also experienced the same thing. This is a slow high-g hairpin taken in 2nd gear at 40-50 km/k and exits into a very long straight, so you floor the throttle as soon as you exit. At the exit of the hairpin I floored the throttle and experienced no acceleration for about 3-4 seconds before the car finally responded again. I pulled into the pits after this lap, and slowly after a few minutes the fuel gauge went back up from 2 to 4 dots again. I let the car cool down and then went home.
Here is the track map:
