Hi all, my 57 plate keeps going into limp mode if I exceed 2000rpm before its fully warmed up (not stone cold!) in first gear. Turn off ignition and back on all is fine, cant seem to make it do it when hot. Fault code with EML is p2127 which is throttle pedal position sensor but I think this is a red herring. Any feedback would be much appreciated.!!

You are probably right that it is a red herring, it could be a poor earth or live connection somewhere. :dunno
You'll need to undo any earth connections and use wet and dry/emery cloth to polish the bodywork and connections to shiny bare metal. You can cover the re-done connection in waxoyl or similar.
Start at the battery, disconnect the earth lead.(leave it off for now) clean the battery terminal and the connector, follow the lead down to where it connects to the inner wing and do that connection. Finally follow the lead to the engine block to do the same. Any earth leads your find en-route treat the same.
There is an earth point on the inner offside wing (behind the ECU) open it up and clean it.
Go back to the battery and do the same with the live/positive lead, following it to the starter motor and any connections between.
The ECU has a big plug on its end, remove this and reconnect, this should be enough to clean the pins. There are some connectors in the fusebox near the ECU, open them up and re-connect, be careful the pins inside are delicate.
Once done reconnect the battery live connection first, make sure both connectors are nice and tight.
Good luck, keep us posted.

It's just occured to me the air temperature may have something to do with it, try cleaning the MAF; viewtopic.php?f=47&t=12607
I've got the exact same problem but mine only does it every now and then and only when cold
Was advised to check/replace the suction control valve (on the back of the fuel pump)and/or the fuel pressure dump value (on the fuel rail)
As yet I've done neather cos it hasn't done it since but it's on my list of to-dos
I also got the fault code for the acelerator position sensor but a Google search of the codes for navaras brought up loads mentioning the fuel delivery
