freelander 1 2.0 tdi hse 2004 engine cuts out intermittently while driving

Hi everyone i have a Freelander 1 2.0 tdi hse 2004 reg 151000 miles on clock and the car drives ok for weeks on end then it will just cut out whilst driving.some times it will restart and some it turns over until the battery goes flat. my local garage thought it may be the low pressure fuel pump (the one behind the off side rear wheel ) so i had it and the fuel filter replaced.but it still does the same thing, can anyone think of what may be the problem. many thanks in advance. best wishes to you Paul.

Rail sensor electrical connector corrosion is the likely cause, unless the overly harness has been fitted.

Thank you very much for your reply it it much appreciated. i am composing a list of possible causes for my local garage to look at.ps the low pressure pump was changed as in my original post.
