Help! My 2002 Boxster S w/Tiptronic is exhibiting some troubling behavior. For the past 2 mornings I have left my home and driven for aprox. 10 minutes and then began to experience surging in the engine before it completely loses power. When the power loss occurs the engine rpms drop to 1000. Further, I lose all throttle response. Thankfully I have been able to limp to the shoulder, turn the vehicle off for aprox 5 minutes, restart the car and no issues for the remainder of the day...
WTF? I am throwing a P1503 code, but cant seem to determine what this is..

Any thoughts????
