Hi Colin,
Just for your info, I have found that on long runs (8+ hours straight) the Evo seems to shut down & I have to start it up again.
Doesn't seem to have any issues restarting, but it is annoying when I am logging the data.
It appears to be that maybe the memory fills & then it shuts down to clear, or something like that. This happens regardless of weather I am logging the data or not.
Cheers,
Basil
