2003 pathfinder, after starting it will accelerate but after it runs a few minutes it dies when you press the gas pedal ? No codes, new fuel pump, new fuel press. regulator, new fuel filer. Gonna try a throttle body ? Thinking it might be the gas pedal sensor ?

Check a few basic service procedures first, before swapping parts as a best guess hope of fixing it. That might work and it might not. No YouTube videos on this. Read page EC-81 of the factory service manual. https://www.nicoclub.com/service-manual ... 3%2Fec.pdf Accelerator Pedal Released Position Learning, Throttle Valve Closed Position Learning, and Idle Air Volume Learning procedures should all be performed to be certain your issue isn't just a basic adjustment problem.
