Pressure test fuel system, test alternator, EGR and pressure test transmission as all these will cause car to stall under load.

And I presume the very first thing you did before you started replacing all those parts was to scan for trouble codes, Right? I'd be going through the wiring harness making sure all connections are clean and tight and that all grounds are also clean and tight.
