2002 4Runner completely shuts off while driving

I've found a couple of other threads on the site but none that match what's happening to my 2002 4Runner. The other day I was leaving for work, backed out of my parking spot and shifted into drive. As soon as I hit the gas my truck shut off. Not just the engine, everything shut off. I had zero power going to anything...lights, interior lights, warning lights on the dash all dead. When I try and start it again I don't get anything...the engine doesn't try and turn over, there's no click, just silence. After about 5 minutes I start to get power slowly. When I have the door open the interior light will flicker and then come on dimly until it comes up all of the way. During this time I still can't start the engine and still don't get any indication that I'm attempting to start it. After another 5 minutes or so I can start it up like nothing happened. This has happened twice in the last week.

I took it into a local shop yesterday and they couldn't find anything wrong with it. Battery and charging system tested great (I got a new battery a month ago) and the only thing they could find was some corrosion on the negative terminal. I have 222,000 miles on my truck and I'd like to keep it for another 200,000 more. Has anyone seen or heard of anything like this? Thanks in advance for your help!

That's definitely odd. Reminds me of the relays in my old '65 Lincoln Continental. If a hot wire ever grounded out...the power would just die until the relay reset itself. There's nothing like that in our 4Runners though.
 
No, no engine washing prior to this. Nothing out of the ordinary (driving to work, gym, etc.) had taken place before this.

Regarding the battery is there any way to tell there could be something wrong with it other than having a shop test it when my truck shuts down again?
 
I assume the shop you took it to cleaned the corrosion? Has it happened since? I bet that was your problem, a bad connection.
 
x2 on the bad connection, visually inspect all your power/grounds and if they all look good it was probably just that bad connection. If they look dirty take them all apart(disconnect your battery first) clean everything with sandpaper then put it all back together.
 
clean your battery terminals (both the truck cable and the battery post) with a wire brush.

even better go buy new $6 terminals from West Marine and install them. You may have to slightly modify the stock end links to fit onto a 3/8" pole but it will be worth it.

it should look something like this:
