So recently the last couple of days i have been driving the dash goes dim and at lower rpm's you can feel the bike stuttering. So I find a hill and turn the bike off and it won't cranked back up, So proceed to roll down the hill and jump it and it runs fine for the next little while, but has happened almost everytime I ride it the last 2 days.
Weird thing is if I let it die then jump it and drive for just a minute I can come back hours later and it will fire up.

Battery gets about 12.8V ignition off and about 14.8V@4000rpm.

If anyone has had this happen a point in the right direction will be quite helpful.

Cheers
