I had a sudden power loss traveling during a gas stop. No light no code. It acts like a lost a cylinder, knock sensor/sub harness or some fuel component. The dealer was just doing maintenance and added octane booster & when I picked it up they had popped my cam sensor bank 1. It's either not metering fuel right, but getting fuel, proper spark or a dead cylinder. Stumped. Had this wet happened to anyone. It's a base model manual with coilovers, wheels & system. All pro done. Stock motor. Stumped.
