Can anyone help?! Important MMM question.

[Ryu James]

So tonight my 2nd MMM died. but here is my question. Both of my MMMs did not die while they were running, like it seems is the case with most of them i read about in the forums. My MMMs simply would not turn on one day out of the blue. The first one I ran about 10 minutes on 3 occasions and then the 4th time i go to drive, it wont turn on. My 2nd MMM i drove 3 or 4 times for about 30-45minutes each time. It ran perfectly too. Never over heated. But the same thing happened. When i got to the track tonight to race the thing would not turn on. The funny thing is that earlier today i checked it and when i switched it on nothing happened. so i switched it off and tried again and then it worked. so i thought it would be good to go. but 3 hours later at the track the damn thing would not come on. These symptoms are making me wonder if there is just some short in the switch or something.

Has anyone else seen these symptoms? Is this a definite failure and how other MMMs have failed or is this possibly a short and can be fixed? Please share your knowledge Brushless Kings! Thanks.
