Loss of power + cannot go high speeds

[potatobroxd]

Was riding normally today and suddenly my bike loses power. When in gear especially at higher gears, bike refuses to go pass 6k RPM and if i give it more gas the RPMs start to drop. It seems like it struggles to get to higher RPMs more at higher gears than lower ones. I can ride at lower speeds but with significantly less power, any clues why?

Bike is CB125f so its electronic fuel injection. Ridden the bike last week for 60 miles and bike was perfectly fine

EDIT: much harder to start the bike now --> takes around 4 seconds to start but idles fine

Could be the fuel pump.
