Is it always ten minutes? Or is it one minute sometimes, five sometimes, ten sometimes, fifteen sometimes, etc.?
Right, if it's a bad connection you'd expect it to be somewhat random. You'd also expect it to turn off sometimes (this is what happens with my depth sounder and spreader lights..).
I don't know, something time dependent makes me think heat. Perhaps there is a marginal, highly resistive connection which heats up causing it to change shape and make a better connection. But it's highly unlikely that it could happen independently on two different circuits.
Do they all come on at the same time? Do you have a voltage meter on your panel, is it reading ok? Bottom line I think you need to get out there with a multi-meter and start following the circuit path. Measure the voltage along the way. At least it's re-producible.

The length of the wire shouldn't be a factor. Remember to keep things straight, low current would be caused by high resistance which would also cause low voltage at your load. You can't have one of these things without the others, ohms law always holds true.
Generally I can't see how high resistance/low current/low voltage would cause a delay - it should result in no operation or flaky operation but not a delay behavior.
