ok. spent 1300 on a certified mechanic to tell me that the fuel pump was not pushin enouugh pressure, but the bad connection between fuel filter and line to fuel rail was even worse. replaced both. runs like new. thanks to all the insight. hope this bit of info will help another troubled soul down the line. as a reminder "when replacing fuel filter, make sure its connected back correctly".
