When it doesn't start it behaves like a dead battery with one click at starter and then silence. Upon releasing key date/time are reset on display, lights are dim, and there is a clicking behind glove box. The clicking and dim lights remain until pressing brake pedal which seems to restore electrical. I try starting again and either repeat above steps or engine starts.
So far the engine stays running and Jeep drives like normal with just one exception where there seemed to be total electrical loss about a minute after starting but then immediately started up again. All power cables are clean and secure at battery, starter, alternator, etc. I am a touched confused and especially bewildered about the magic brake pedal...
Previously I had noticed the radio losing power momentarily during right turns out of driveways but nothing else was affected and it has only occurred 3 or 4 times over a few months. Most likely unrelated to primary problem described above, but since both problems feel power related I thought there may be a connection so worth mentioning.
I always seem to encounter the odd problems that takes forever to identify cause so any input, suggestions, and of course help would be immensely appreciated!
