Vape Connexx 150 problem

[SirVapesofChutney]

I have a VTM 150 watt vape connexx and it worked amazingly for about 6 months. Now for some reason when I turn it on it automatically goes to 30 watts which is fine. but when I turn it up past 30, with any build, any coils, or any temperature setting, after a couple of hits it goes to the temperature setting, or it goes down to 3 watts all by itself. Anyone know why it is doing this and if there is something I can do about it?
