check for problem coil/s and ignition control module
the indications that an electronic component is failing when it gets hot and causing intermittent spark

Classic failure that I have experienced twice now while riding a 2007 Suzuki C90. Both times the bike went totally dead electrically while going down the road. In both cases, I sent a fellow rider off with my battery, to buy a battery that fit. That's how I got home, with the ignition system running off of the battery alone. The old battery was the first bad actor. It shorted out internally causing the regulator rectifier to call for max amps from the stator, burning the stator up...melting windings...both times. Replace the battery with a high quality battery, and replace the stator and rectifier/regulator with top end stuff...like Ricks Motorsports. Yes it costs three times as much, but it handles three times the wattage. Don't go back with OEM parts like I did the first time. It will fail again just after the warranty expires.

probably needs a stator and regulator rectifier. check battery connections first

Drain the tank of the old fuel completely, try to drain the fuel lines as best you can. Whilst the tank is empty, if you can remove the fuel pump and clean out the filter for debris or gunk. Pull out the spark plugs and see if they have fouled, don't try cleaning them just replace. I have found once a plug is fouled, it is best to just bite the bullit and buy new ones as issues can happen again.

Locate the drain screw on the bottom of the carburetor float bowl. Drain the float bowl's contents into a clean container, if possible, so that you can see if there's any dirt, rust, or water in the fuel.
