Yamaha YZF 600R Thundercat does not start

Moin moin friends, yesterday I drove with my Thundercat about 15KM without any problems. Then she stood up for about 2 hours, she jumped normal, but after about 100 m she just went out without jerking or anything like you just turned the ignition key. The only thing she still does now is on ignition and try to get the oil level warning light on and that was it. No starter turns, no petrol pump clacks or anything else. The starter turns, motorcycle starts and both lamps go off. Does anyone know this mistake or can give me any tips? Thanks already for your help
