I'd say it was the glow plug controller, mine has started doing it too, but I need to find if it's one, several glow plugs, or the controller, so you might want to have the codes read.
The controller is about £100, and each glow plug is about £19 plus VAT
Mine only does it when it's 5C~ or below - is yours the same?
