Many reasons for them to drop out unexpectably both self inflicted by quality issues and externally by the severe operational conditions.

X2 on the Injector Spray Pattern issue on the Filament/Loop type Glow Plugs.
Pic of what is in the Factory manual.
More normal issues are simply how you drive (does the type of driving you do build up more Carbon; like only low Speed City driving).
How, often do you need to use the Glow Plugs. A recently rebuilt Engine may not need much Glow plug use to get it going. A worn Engine may need several applictions of the Glow Plugs to get it started.
