Make sure you have a good, fully-charged battery installed. Look for loose power connections between the battery and main breaker and Power Distribution Panel. But my first thought is that you might have the output of one of your motor controllers shorted to something that it shouldn't be. Or maybe you have the wires crossed between the two CIM speed controllers, and the difference in timing when the program is run at startup vs. being run interactively makes it a problem.
