I have a 2005 Harley sportster 1200 FC custom driving down the highway today and 70 miles an hour all of a sudden the drop-down about 10 miles an hour and it felt as if I lost a bunch of power when it stop it stays running and it fires up if he shut it off however the back jug doesn’t seem to be getting full power I don’t think it’s fuel because I think it may be electrical wires coil does anybody have any suggestions please if you do email me
