2012 Daytona 675 Starting Issue

Good Morning! I am here with an issue that I have been having and I'm not really sure where to go. I recently bought a 2012 Triumph Daytona 675 and everything has been great minus one issue. After I have been riding around the bike cranks really really slowly. When the bike is cold started it has absolutely no issues at all but when it is heated up it cranks super slowly kind of like if the battery were about to die. I since replaced the battery and I am still running into the same issue. I am not sure where to start down this parts rabbit hole. I've heard its the starter and I've also heard it could be the stator and I just wanted to get everyone's opinion before I start throwing parts at it. Thank you for your time!
