shut

I have been racing this thing for 3 years now and i find i am just getting slower, mainly due to lack of confidence in the damn thing. I feel like every weekend i am hunting for some random issue. Last round all seemed good until 1/2 way though morning practice the bike just lost power and died...

I have about 600 miles on my 2017 RC 390. A couple of days ago the engine shut off in traffic in second gear with clutch pulled in, the bike started back when I release the clutch. Today, I just started the bike to warm and it shut off after a minute of idling. I was wondering if this is normal...
