Hi, my YZF750R stooped while riding the other day. I have initially checked fuel filter, pick-up, carbs etc and the fuel system appears to be clean and functioning properly. Now the bike will occasionally start, run for a couple of minutes, then die abruptly without any coughing or spluttering prior. After this I am unable to start it for a few hours, when it will do the same. I am thinking this is electrical but have no idea where to even begin. Any suggestions will be greatly appreciated!! Thanks.
