My 2000 Durango always has a hum in the back from the fuel pump. Cold or hot. It's always struck me as a little noisey, but it's never been a problem in about 125,000 miles.
The dieing at idle sounds to me like an idle validation issue in the tps. I've seen other Dodges have tps problems and not set codes.
The other option would be that the pump is dieing and dropping pressure. However, that should cause a problem under acceleration, not at idle. Note: the pump uses fuel for cooling, so it's possible that fuel level could cause the pump issue. (GM trucks have the problem and are notorious for the pump dieing due to cooling issues.)
You mentioned water in the fuel. While this can shut the engine down, it will normally misfire and generally run bad before that happens.
