Traction Contol Cuts Out When Unit Heats Up

Clark TM15S

I am having an issue with the control system on this truck. (Cableform) 48V
The truck shuts down after it heats up. The system will start again after just a few minutes and it doesn't give me enough time to troubleshoot the problem. I have taken the temperature sensor out of the equation by jumpering the ends together. The truck continues to cut out and I am looking for any sugestions.

Check the drive motors,power cables,and contact tip. If any of them show signs of overheating,or the drive motor comontators and/or field windings for shorts or burnt-up, then replace them. Next would be to check out individual components on the SCR panel,using a handyman tester.Also test the thermal protector,for to high or low resistance.
