I have a MM with a full 5s pack problem like that. It runs on 5s well except for if the pack is totally topped off. I actually found that my solution was to set my charger to 4.15v/cell rather than 4.2v and it works with no issue. If I have a fully charged pack I just hold the truggy in the air and let then motor run for a minute or so. Somtimes it take shutting the MM switch off and on again and running it untill it quits, then doing it again untill it stays running. Kind of a pain, but then it runs fine after the peak is taken off the pack. Its wierd, I have 3 MMs running 5s and only one of them is that way. The other 2 run 5s fine with no problems.

That was the only solution I found. If you find another solution let me know Id love to find it also.

Mine doesnt have any cogging or heat issues like yours though.
