When I'm driving after a little while doesn't shut off but when pressing gas it doesn't accelerate. I've replaced fuel pressure regulator, fuel pump and fuel filter.

Hello,

This could be a problem with your throttle body needing to be cleaned. While moving the amounts of air that your vehicle needs to ingest to run your vehicle's throttle body will get coated with a black "gunk" called coke. This coke will get all over the bore and throttle plate and interfere with the signal of the Throttle Position Sensor (TPS). Without a clear signal from the TPS your vehicle's Power-train Control Moduke (PCM) will go into "limp mode" to keep your engine from going lean and blowing up. I have included a couple of diagrams down below for you to go to:

Please go through these guides and get back to us with what you find out.

Thanks,
