Help! My RE 500 Bullet is sick 🤢

Hi everyone, I hope you are all well. So, here is my problem... I was starting off from a stopped position On my RE 500 Bullet and driving each gear to the limit to get max speed, but when I got to third hear something blew and I lost all power and the bike cut out. I started it again and it went fine until I got to third gear again and same thing happened (lost all power and bike cut out). I was able.to.drive.my bike home using just 1st and 2nd gear ( lucky I was close to home). Can anyone offer me some help in solving the problem, thanks in advance
