2001 Dodge Van 6 cyl Two Wheel Drive Automatic

2001 Dodge Van,
Engine blogs or hesitates during acceleration while driving or in park. There's no engine check light. It's starts up fine. Just only when I accelerate, it acts up. I already replaced the TPS sensor and had a fresh tune up 6,000 miles ago. I'm leaning towards the fuel pressure regulator but not sure. Any suggestions please.

Lack of acceleration, chugging, hesitating, bogging, misfiring etc. Could be caused by one of the following 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.
