It died on me on the interstate, tried to restart and acted like battery was dead, charged up the battery and still wouldnt start. Got it towed home, we have changed fuel pump and fuel filter, still wouldnt start. It ran for ten min then died again. Ran codes, got po141 o2 sensor heater crt 1 sr 2, p0147 o2 sr htr crt bank1 sr 2, p0300 random misfire, p0325 knock sensor, p0505 idle air sontrol system, what should I do now to get her running again, thank you.

From the codes you listed, the idle air control valve, or throttle position sensor is what I would check or replace first.
