2017 yz450f launch control problem?

Goodmorning I think I am having launch control wiring issues when I kick the bike over the light doesn’t flash and once I wiggle the wires around for it it does and it also starts when I’m riding it if I was to ride a bit hard it would die on me like it’s losing gas but if I ride easy it wouldn’t could this be a problem with the launch control? I have videos also thanks btw I bought the bike like this but when I test
it ride fine
