Vespa GTS Super Sport 125 ABS dies while driving

Hi people, despite Sotwareupdate in October 2020 and since then I have not driven 200km again problems with my Vespa… engine runs round, dies at the stand (e.g. at the traffic light), then jumps bad and the Motokontellleuchte no longer goes out.. In the end the box dies then even while driving away while the gas takes off… J Ma the new start quite worrying noises- a clacker, when turning off it runs after … I bought the Vespa in May 20 , just under 1800km on the clock – I would like to light the beautiful box …. just feel like I’ve tossed just €6000 for the ton… Does anyone else have such problems, or an idea what can be (I don’t rely on statements of the general impotoeur anymore after he obviously can’t solve the problem…) Constructive advice would be.me A help – or a match…
