2000 Mercury Sable 6 cyl Front Wheel Drive Automatic 125000 miles

Every once in awhile my car while not going very fast my car will stall, (not sure if that's the right word) but I can't accerlate. What I've done is switched between neutral and drive and sometimes that works, otherwise I have to put it in neutral and restart. It's only done this a few times in the past year and it happened twice the other day, but since then it's been fine. I changed the spark plugs awhile back because someone suggested that may help but obviously that was not the cause. The only other thing I thought of possibly is the fuel pressure regulator. Any ideas?

Do you
have the same problem?

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

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.
