Running a 509 with a 177 blower, 1080 Dominator. Motor runs great and on the dyno made power to 6100-6200 rpm. The problem I'm having is: it will be running fine and at no given time when at 4500 and over it's like someone turned the key off. Does not feel like it's fuel starvation as there's no popping, backfire, studder.... it simply cuts off but if I get it to neutral fast enough it picks right back up on idle and then will run fine until the next time it happens. It happens often but at no given time where I can pin point it and make it happen at will.
