This sounds like an interesting problem.
The first thing I would do above all is check the current draw through the two drill motors, this could be the problem. Its possible something is causing the motors to stall out and draw tones of current making the speed controllers light go dim.
When solving any problem you should make a list of all the possible problems starting with the simplest down to the more complex.
Ex:
#1 Check for a short circuit.
#2 Check all wiring, possibly rewiring the robot.
#3 Try differnet motors for testing reasons
#4 Check speed controllers
#5 test outputs to the speed controlers
I think you get the idea,
It really sounds like there is a short circuit on the other side of the speed controllers between the motor wiring and the speed controller.
