Can be a few things. I would suspect a vacuum leak. Start by replacing all vacuum hoses. Replace one at a time, so as not to get confused. Very cheap repair. Also replace the spark plugs and wires unless they have been replaced within the last 50,000 miles.
If a Volkswagen Jetta loses power while driving uphill, one possible explanation is that the mass airflow sensor has gone bad. Another possibility is that the intake manifold could be clogged. The only way to know for sure what's wrong is to take the car to a mechanic.
You're driving an automatic, the car should select the correct gear for you. However some automatics allow the driver to select low gears for use in slow moving traffic for example. If you feel you need more power when driving uphill then select one of the lower gears.
