New to me 2006 Cayman S. 24,000 miles. Noticed that suddenly, complete loss of acceleration, no response from gas pedal. If I release the pedal, it will then accelerate normally. usually happens after going around a corner. Can be in any gear, but usually around a 90 degree turn, left or right. Can be from a stop. No codes thrown. 1 instance of a PSM failure, which disappeared after shutting off the motor, and then restarting. Good, gas, full tank. Have seen some discussions about steering angle sensor, wheel speed sensor, and/or brake pedal switch malfunction. Car feels like traction control/PSM is activating, but will do it with the PSM turned off.
Any ideas? At my indy right now trying to figure it out.

 

Any pending codes?

Absent any pending codes it kind of reads like there's break in a fuel line in the tank and under g-forces the fuel supply to the engine gets interrupted. Doesn't have to a be a complete loss of fuel just a drop in fuel pressure.

 

No codes, either saved or flashes while driving the car and having it hooked up to computer, even when the pedal went dead. Steering angle sensor was off, reset, but didn't fix it. Had them change the brake pedal sensor, and so far, that seems to have been the culprit. Will see as time goes by.
