Today I've narrowed it down the the computer box. If power is lost, I open the hood, tap once or twice on the "brain" and power is restored. When I unbolted it, to check on battery connections, a bunch of white dust / corrosion fell out of the connection ports. I'm wondering if I should disconnect all four connectors and see if I can blow them out and attempt to clean the connections? If nothing else, I could see which one has the corrosion and then narrow down which sets of wires I should be tracing to find a problem.2012 4 cylinder</blockquote>
