My first guess would be a failing fuel pump. You need to check the fuel pressure with the key on/engine off, and then with the Key on/Engine on.
If the pressure drops significantly after you start the engine, then either you pump is bad, the fuel pressure regulator is bad, or the fuel filter is clogged.
This is only a guess, as I can't diagnose this from here. But if you need more help, just ask.
