Hey guys , have a power loss issue. Rode about 150 miles yesterday. After running the bike for about 20 minutes, at steady speed say 60mph at 3700 rpm , bike will lose power and RPM will drop instantly to 1200 or 1500 RPM for about a second or so. If throttle position is held bike will come back to speed. Does not feel fuel starved. Definitely feels like a electrical issue. No fault indicator light. Any thoughts would be appreciated. I was thinking a possible coil issue
