This TD is usually very reliable.
It sounds like this has been a slow degeneration (it's happened before and you've been luck it has finally started)
The one thing a diesel does need is heat to get it to start, If the vehicle is cold, that heat is provided by glowplugs, and these glowplugs stay on until the temperature of the engine reaches 50C.
I would check that the glowplugs are working, and not just that the glowplug light illuminates and goes off.
If you know what you are doing, you can jumper from the battery hot terminal to the glowplug rail for 10 seconds, and then try starting.
If it goes, you know the glowplug relay is toast.
If it doesn't go, then one or more glowplugs are toast.
If the glowplugs work, then you should look at fuel delivery to the injectors.Start with a new fuel filter.
Hope this helps
