Define "cease to function". Is the robot still powered on? Do you have comm? Is your main breaker tripped (that would take A LOT)? Is it no longer responding to signal? Is it pausing while it attempts to make turns?
Are all six of your wheels on the ground or 4?
There's always the simple stuff: Have you checked your wiring + to + and - to -? Are the proper breakers in place on the PDB? Are your motors all spinning the correct direction?

Were your wheels mounted right? You could have had them on the wrong side and (speculating) were stalling the motors because the wheel force vectors were canceling out.
