Guys I need some help. My motor will crank like a champ and runs great for about 15 minutes. After that at full throttle it bogs down and dies. It will crank right up every time after it dies and will idle or go forward very slow but as soon as the throttle is opened up it will die.

Newly rebuilt carbs, new fuel lines, new fuel pump kit, new fuel filter, new tank, new plugs. Doesn't seem like it's a fuel supply issue since it will run great for 10-15 minutes and then problem starts. Could this be a coil, power pack, stator issue?

I'm certainly no expert and at a loss now so would appreciate any help. Thank you in advance.

Hook a timing light up and see if spark goes away when this happens, if so the high speed side of stator need checked..
