I stopped at a shop on my way home from work. When I went to re-start the Jeep
(4.0), the engine did not turn over and the car made a quiet buzzing noise
(from within the dash?) which slowly died away - as if something was
dis-charging. Then all power failed. I raised the hood, and wiggled all of
the "fuses" in the power control box and the power returned - even the
headlights would shine. But when I tried again to re-start the engine, it
would not turn over, and everything electrical would immediately cut-out, until
the process was repeated. Maybe it was just from leaving it to momentarily
build power, again.

The car was outside all weekend while we were camping, and the battery never
faltered when I left the site, nor when I left from work this evening. We're
supposed to get more snow, tonight, so I need to move it, soon.

Suggestions, please?

Thanks

First check for a loose battery connection
and check the electrolyte in the battery.

Your batter might have lost a cell and that
will cause all sorts of problems.

However, since you jiggled the power center I'm
also tending toward a failed ASD relay. If it
dies or fails your vehicle will not start.

You are describing a loose r really corroded main power cable. Likely
right at the battery.

The cables are clean and tight. I returned 3 hours later & it repeated the
same behavior. The lamps burned bright when the power would flow. It does
have its original ('98) battery, though....

A few minutes later, it started as if nothing was wrong. Driving home, the
ammeter read just above 14v, as usual.

I just finished shoveling that snow, so now I'll go check the battery's fluid
level, clean the terminals and cables. i'll also keep the ASD relay in mind.
Thanks, guys, for the replies.
