1998 BMW 740 V8 Two Wheel Drive Automatic 137000 miles

1998 BMW 740il, driving down the road - tried to accelerate and now it wont go over 2000 rpm. It feels like it is missing really badly. What could it be?

Possibilities: Inspect and test all the following listed below: Oxygen sensor.
Catalytic converter.
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Crankshaft position sensor
Knock sensor
Manifold absolute pressure sensor.
EGR Valve
Fuel pressure regulator leaking or defective fuel pump.
False air leakage.
Fuel contamination.
Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.
Incorrect ignition timing.
Cap and rotor.

Note: If it doesn't apply disregard it.

It sounds like the fuel pressure is possibly the culprit.
