Yea i had this problem earlier this week... I took it in and they called it the "hard start, hot soak" problem.... to fix that problem they replaced my ECU/PCM/Fuel Pressure Regulator... not just replaced with the same parts, but they upgraded the ECU/PCM/Fuel Pressure regulator so you shouldn't have the problem anymore... my car has been running great now. This also happened to someone down in Cali.... they had the same problem about 2 weeks ago....
