i just rubuilt my engine with everything new and broke it in properly, when i take it for a ride it runs great but sometimes when im out on the road it will run great through the powerband then all of the sudden when the powerband kicks in it dies if i let off the gas it will idle and run slowly but when you hit the gas it dies. if i stop and let it set for 5 minutes and restart it with a lot of kicks kinda starts hard but then it runs good no problems at all i have no idea what is causing this.
