fix EPC problem

I have a 2017 Volkswagen Jetta with 40,000 miles. The EPC light came on yesterday when I started the car. It drove fine for about 40 miles. I stopped at the store and when I tried to start it again the engine initially turned over, but died within a couple of seconds. The car eventually started, but it didn't have any power. I could drive the car (at less than 5 mph), but the engine sputtered. The engine would rev to 3000 rpms, but quickly drop to a little over 1000 rpms. I started the car this morning and the engine still acts the same, but now I have an engine light as well as the EPC indicator. Are there easy things I can check before I take it to the dealership and what are the most common reasons for the problem. Thanks, Rob
