ENGINE "CHOKING" FROM DEAD STOP

What would cause my truck to occasionally "choke out" from a dead stop and idle roughly when engine is warm but not hot. It hasn't completely stalled yet when it "chokes" but it leaves you in the intersection for a couple seconds. I have already had the PCV valve, EGR valve and PFE sensor replaced but it did not make a difference.

Here's other suggestions of mine

Check and test 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.
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 and keep testing.
