Sounds like you have a couple of things happening, have your battery tested and recharged if good, then pull the codes, looking for an IDM code, if it is there then replace the ignition module and distributor stator, then test the fuel pumps pressure and flow rate, these rigs have 2 pumps, 1 is in the tank that is your lift pump and the high pressure pump in the frame rail, if those check good then check the fuel and ECM relays and their wiring, pay close attention to the grounds, then move on to checking out the other codes, make sure you reset the ECM after repairs are complete so it can relearn the repaired systems and your driving habits.

Now that the engine controls are fixed then you can check the charge/start system, the alternator should be putting out close to 14.2 volts at idle, if it doesn't double check the belt tension and retest if still fails replace the alternator.
