MMMv3 lost configuration while on track

[Smashwings]

MMMv3 lost configuration while running at the track the other day, and only steering worked, no throttle.
It was running good for more than one hour, I tried manual configuration but didn't respond,I had to return home and when I linked it, it worked again.

There is a way to avoid this?
