1.8 TD (BJ. 97) Tuner – no longer starting

Hello you love, and I have been having a big problem since just now, because I started the car quite normally to drive my daughter into the kindergarten and everything ran normal, then I switched into the second gear and speeded briefly he then took the gas and suddenly the speed completely dropped and the engine went off. In the attempt to start again I fell on that the starter works but one does not hear an ignition attempt from the engine so I go the Assuming that he doesn’t get a diesel but how can that be all at once? Do you have any tips or ideas about what I can have the ADAC human being look for? Greetings and thanks Tobi
