    car quits / dies !

    2005 Magnum R/T 5.7, did MDS delete, heads reworked and small cam (comp cams stage 1). 3200 FTI torque converter, 6.4 injectors, shorty headers and 3" dia. exhaust. Car starts and idles for a couple minutes. Restarts, idles for 2 or 3 minutes and dies again. I'm thinking throttle body issue but can't pin it down. Throttle body is new as is EGR valve. PCV disconnected, will not idle with pcv connected. Any help greatly appreciated.

    moving ahead

    Bumped up RPM with limited success. Had stock 5.7 injectors cleaned and flowed. Will be changing them out.

    Thinking maybe sort of a flooding situation, occasional p0172 and p0175 codes. Mostly no codes.

    Bumped up idle again with some success. I'm thinking as the idle settles down, voltage drops and shuts engine off. Also adjusted up alt output.
