There are a few components that could be causing your problem. You may want to start by doing some voltage testing on the battery and the alternator. If you know your alternator and battery are good, look at the drive belts. Make sure they are not slipping or damaged. If all of that passes inspection, you will want to turn your attention to the fuel delivery system. Check the obvious fuel pump and fuel filter. Malfunctions with these can lead to low fuel pressure and symptoms similar to what you are describing. Another component to check would be the throttle. Drive by wire sensors can cause issues like these as well. Most of these sensors however will set off a diagnostic trouble code and alert you in one way or another.
