It is normal to do that in P,,you do not have 5 gears it is 4 speed box,,not that this matters. When it cuts is it instant or does it splutter as though it was out of fuel

If it is instant the the fault must be around the fuel pump relay,,as it is this that has the limiter on it here 26 in this link,,but without checking the fault could be else where

its basically like the limiter is meant too be at 4 thou rpm.. almost like a safety mode?? going too change the relay.. checked plugs they seam ok.. leads are slightly rusty.. but i dont think this is problem although im not sure.... its slowly developed over time and hasnt just occured either..

hope the relay works :-(

as it's going into limp home mode there will be fault codes available to read off the diagnostic plug.

Go to merc indie to get the codes read as a first step.
