Managed to slowly get back to the pits, cool down and go back out, but having the power just disappear like that was quite disconcerting.
I had coded the "engine power reduction to prevent brake overheating" feature out myself the week prior, so it didn't seem like that was the issue. I double-checked and verified this when I got home from the track the first night.
Removed my AA tune and went back to stock, and did not have any problems the following day despite running faster laps. Spoke to people at the repair shop at the track about this, and their conclusion was the same, that the engine probably got hot and started pulling timing and the tune was not helping the situaiton. Will hopefully get a revised tune and test it out at Watkins again in Sept.

High coolant temps = knock/timing corrections = loss of power
