Weird LRP related issue
So im having some crazy problems with my AI LRP speed control. Im running it in a VTA car with a novak SS 21.5 motor first off and a 33/83 gear ratio giving me a final drive of like ~5.0. The problem Im having is that after about 10 minutes the car shuts down for about 5 seconds, flashes its light on the speedo then will run for about a half lap and do it again. When I temp it, its only temping @ 120 degrees on the motor and about 100-110 on the speedo. I've tried 2 different batteries making sure to eliminate that as a possibility. Every once in a while the speedo will also just randomly reverse itself. What could I do to solve this? I opened up the speedo and there was some carpet fuzz in it, so I cleaned it all out.
