I was having similar issues with my 408LS. Off idle it would sputter and fall on its face but would eventually open up and definite power loss at all rpms. Only code it would throw was Random Misfire. Changed coil packs, changed map, crankshaft and camshaft position sensors, new plugs and wires still no change. Fuel pump was good at 65 psi and checked filter. Finally came down to the fuel injectors. Took them out and clean them with B-12 fuel system spray cleaner and they were completely filthy. All kinds of black trash came out of them. Finally just decided on new injectors and that was my problem all along. Runs perfect now. Just saying.
