Hello, it is possible that the pump is going bad but, it sounds more like water in the fuel or a dirty filter or dirty injectors. I would try a fuel additive first to see if that will clear your problem. Let me know if you need any help. Good luck.

SOURCE: stalls and wont idle when cold
Re the trooper. You have a couple of possibles. The most likely is the glowplugs or glowplug relay. Don't be fooled into thinking glow plugs only heat to start - the also do whats called postheat. That is to raise the cylinder temp until the block is warm. IF they are not functioning (clip a light onto one whilst switching the glowplug on to test the relay) this is common.
Most likely is a stuck EGR valve - stuck open so running a very lean mix when cold. Its two bolts on the inlet manifold, pulls out and looks covered in soot - it should push in and spring out. Can be cleaned in petrol or alcohol or with compressed air.
More remote is possible you have a faulty injector...only really testable by an engine centre...
