04 GTP. If I accelerate quickly - Ding Ding "Reduced Engine Power" and I have to turn off the engine and wait a minute. Starts right back up and the Check engine light goes off. No problem on regular driving or smooth acceleration. Happened once when on Cruise control in the fast lane and we started up a hill where it applied power. I've cleaned and checked the MAF, throttle body and the air hoses to make sure no leaks or dirt.

Wondering if the is the throttle position sensor. I read that if one of the 2 position sensors (fuel peddle and throttle body) are off a certain % of voltage, it senses that one of them is bad and it will shut down. Can you tell me if this is true. If so, Ill replace them one at a time and see if it solves the problem.

Thanks in advance for the help.
