Diesel can go waxy in colder weather and gunk up the filter, its not a lot of money to change and worth a try...
If it cuts out it may also be a cracked filter housing, sucking air into the fuel system and cutting the engine out.

Something else to think about is maybe the fuel pump... My old 1.8TDCi focus starting hunting (revs up and down) in the cold weather and was like that for a while, then the fuel pump blew up and took the fuel system with it!
Thing is, these symptoms can be caused by so many things its hard to diagnose

then a rather sad trip to the dealers... That then pulled the filter apart and said it was full of metal swarf... which had then got thru the filter and damaged all 4 injectors...
The pump in colder weather was struggling to pump fuel as it was basically falling apart inside, and then in turn the knackered injectors werent pumping at the right times etc... it really was a mess by the time id finished with it lol!!
They said the only way forward to guarantee it would be ok was to replace the whole fuel system and flush the tank...
They replaced the filter and some other bits before this diagnosis though...
I blame the tuning box i had on it personally, ramping up the fuel pressure etc...

if the fuel pressure gets too high it will lower it, unlike with a box where it thinks its too low so turns it up... if its too high, it probably reads normal on the cars ECU...
I'd be VERY surprised to see a box get anywhere near 140 lol!! Torque is good tho, mine gave a massive jump in torque but bhp was only 10bhp!!
