MMM shutting down

[Rnemhrd]

I have a first run v3 that is new. I have it in a shash 4x4 with a 1410 1y on 2s. It has been shutting down, sometimes re-arming with only the steering working and sometimes working as normal, and sometimes just re-arming over and over.Bumps will also shut it down. Does it on all my 2s packs. No on off switch and my solder joints are all good. I have heard the traxxas servos will cause strange issues, but doen't have one to swap out. Any ideas? Thanks!
