the last week i have had two episodes of total powercut on all motors,with crash from about 400feet as result. both times the i have got back the power for a second a few times on the way down. I have used different battery,so thats not the problem.
I had a onboard camera,and a second after first crash,i can hear the esc power up (beeping as when i connect the battery)
I have concluded with one of four reasons:
* powermodule-problem (three weeks old)
*APM (three weeks old 2.6 running 3.0.1)
*conection-break in powerdistrubationboard
*connectionbreak in battery deans-plug (new and different plugs)
Is there anything else that i dont see,who may have caused the problems?
Both times happend when flying in stabilize-mode
I flied about an hour between theese episodes,with no problem.everything seems perfect!

Have you checked under the shrink wrap on the powermodule?
I had one that was only held together by the shrinkwrap which I detected when I lost power while moving wires. This was brand new and one of 3 purchased.
Genuine Deans plugs are good but the many clones about have real problems maintaining contact, especially when pushed all the way in. I have been using them for years on model aircraft and it is a regular occurrence.
Bullets or XT60 seem to be a better option.
All my power loss events have been when using deans connectors on my batteries. When connected i would move the battery wires and see the APM lose and then regain power. I changed to XT60 connectors and no longer have any problems.
