I am running A005 tires. Technically, I only ran them for one lap (since I just got them). Since it was lap #1 (on new-to-me tires) I was not pushing especially hard.
I have a properly functioning accusump, so oil starvation should not be the issue (plus, I don't believe I was pulling enough G's to invoke oil starvation). When my problem happened, my first thought was oil. I changed the oil before the event and started panicking that maybe I did not tighten the drail plug. Upon inspection, my oil was fine.
I thought about fuel starvation, but my issue seems way worse than fuel. Unbelieveably loud metal-to-metal sound coming from the engine and the motor continued to run through turns 3, 4 and 5 (the sound got progressively worse and louder). I killed the engine after I crested the top of turn 5 and coasted onto the dirt on the right. Other than the initial sputter in turn 2, the engine did not sputter through turns 3, 4 and 5, but the engine would not "make power". It somewhat held power, but pushing down the accelerator resulted in the loud metallic rattling. It seemed like I had fuel. Plus, my fuel tank was completely full.
