It could be either. The reason I asked about the manual transmission is because the torque converter may be staying in a lock up mode. But that would be like just letting the clutch out and killing the engine. As far as the fuel pressure, it could be a problem.
Here is a how to for checking pressure and the regulator. It is both a video and directions. You will need a pressure gauge, but most parts stores will lend or rent them to you. Check it and let me know what you find. Also, let me know if the check engine light has come on and if you are able to drive it if you keep your foot on the gas.
