VW LOSING POWER

2002 Volkswagen Jetta • 4 cylinder 2WD Automatic • 15,200 miles

I have a 2002 vw jetta that will lose rpms and die while driving. When I pull over and restart it, it fires right back up. At first it only did it once or twice a year, now it does it almost everytime I drive it. Of course it won't do it for the dealership! It seems like it mostly happens in the first 10 minutes I'm driving and especially if I'm going up hill. Thanks!

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.
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.
