Pathfinder "cuts out" at 2,300 rpm

Bad ignition module high rpm section.

Ok I need some clarification here. Is it surging/chugging when accelerating? Is it having shifting issues? All the time? Or do you mean it misfires/cuts out at high rpm? (I assume you know there's a rev-limiter that will cut cylinders to keep engine from over-revving). What rpm does it cut out? Is it happening intermittently, or constantly? Also, is the car modified/raced and what condition is the engine/powertrain? Do you have mostly stock Honda tune-up parts in it? Honda's don't perform to their potential with cheap aftermarket plugs/wires/ etc. installed. Start with the basics here. Check the ignition system, fuel system/pressure, etc. Could be bad fuel too. Did you fill up at a small rural no-name station recently? Good luck.

Engine ECU is provided with a high RPM ignition cut off. Perhaps that is what is confusing you. When you accelerate at a fast rate, probably you get higher RPM's and the ECU cuts the ignition to protect the engine from damage.

If you experience a sudden failure in any drive line component the because you have you foot hard on the accelerator the loss of resistance on the crankshaft will allow the engine to rev up un controlled until an over rev sensor cuts of the electronics. Find the reason for the sudden rpm increase from fault codes and replace faulty items.

You mean coils for plugs?What is RPM how high?A Fuel filter is new.next is a crankshaft sensor.

Are you shure that it isnot overheating?

ur having fuel supply or poor electrical supply problem thats why the engine cuts off underload/ check spark plugs or airflow meter condition as well....
