It only happens when I stop at a red light or generally at low RPMs, usually just as I am taking off. Afterwards when I try to start the engine up it needs like a minute or so before It will start again. This happens quite randomly, it can happen three times in 5mins or once every half hour.
The glowplug light indicator was on when it first happened. I have done a little bit of research and it could be the fuel pump relay, crankshaft position sensor or maybe the glowplugs?
What do you think?
