If more info is needed i will be happy to provide what i can.
It sounds like your float bowls are filled when you first start, but are not be replenished fast enough when you give it throttle.

So I would assume a fuel delivery problem. Check any fuel filters you have. If you don't have any filters (you should) then maybe the fuel intake passage is blocked.

Also - Check the fuel petcock vacuum port maybe it is not opening all the way.
