Overworked jaguars

[NS_Radication]

Our jaguar on our conveyor belt will run and then stop after a few seconds. There is a minor mechanical problem, but there is friction acting upon the motor. This is a CIM motor on a torque setup with one other sprocket with the conveyor belt attached. I ran into this problem when they were ready to test the shoot (a two wheel apparatus on a CIM motor) and the wires would get hot and sparks were arcing from the battery due to friction. This was because of a speed gear setup. When they fixed it, it was on a jaguar. When the motor hit full speed, the jaguar was overworked and the jaguar had a slow blinking light for about 2 to 3 seconds and it would go back to normal. I determined, on accident and with a mentor realizing the issue, that when you slowly work the motor up for a few seconds and hit full speed, then the motor will run for a long time. With the conveyor belt, I feel that there is too much friction because it would either run or twitch the chain at random points in time with the overworked red light. Any suggestions will be very helpful!

Thanks in advanced and Happy Competitions!
