Could you provide us with more information please?
What is the revision number of your hardware (it is viewable in the APP)?
What version of the software are you using?
What revision are the digital chips you are using (likely G or H)?
Rev G chips have a large capacitor mounted to the PCB (yellow/blue packaging), Rev H have all nice small surface mounted components (grey packaging).
Could you also upload a picture of where the powerbase is located on the track?
There could be a combination of issues that have created a "perfect storm" here...
