New Guy with issue

[cpbstring]

I have a 150cc gy6 motor in my kart and it starts and idles great but under load it will stall out in about a minute. It will have to sit for a minute before it will start again and the pattern repeats. I have cleaned the carb jets, replaced the CDI, fuel filter and air box with filter - just looking for more trouble shooting ideas as I am a newbie

When it dies, do you have spark?
