You said : "It also cranks slower while trying to hot start vs being cold."

This indicates that here is a voltage drop somewhere in the system. This means there is also lower voltage to the coil when hot, which weakens the spark. I would make sure all of the cables and connections are good, but I suspect that the starter itself may have a problem when it gets warm. I had a similar problem and changing the starter solved it. The bushings and bearings get worn and you never know what might happen.
