More Power Loss

Hey guys,
I've been having an issue with my jeep losing all power. I think it may have started from a short in a faulty relay from my KC's. I live on the ocean and have replaced that relay twice due to corrosion. I was driving about a month ago and turned on my KC spots and my 02 TJ just completely shut off...engine and electric. I was doing about 60 on an unlit road with no other cars around. After 5 seconds of complete darkness the electrical came back and i was able to start the engine while rolling in nuetral.

I pulled the relay right after that and did not have any problems until a couple of weeks later when i put my key in and everything died. The battery had good charge. I would turn the key and it would sond like it was about to turn but then everything would shut off and come back about 5-10 seconds later. When it came back everything electrical worked fine until i went to turn the ingnition. I repeated this for a few minutes and it eventually started.

My error was not getting this looked at. It's been running fine since except for today. I went to start it and everything was dead. My odometer would come back after about 10 seconds....but as soon as i would apply power to anything, everything would shut off. Every once in a while the gauges would dance as well. It's pretty dead in the water until i get it towed.

Is my best bet to keep checking all the grounding?

Any suggestions or probable causes/answers would be much appreciated.

How are the lights wired?

Have you checked the battery cables to make sure they are clean and are on tight?

Even a shorted relay wouldn't kill the vehicle power. Most likely that was due to a disconnected battery and/or alternator. Check all of the connections to those for corrosion. Some vehicles will die of the battery is removed from the loop. And turning on your lights may spike the draw enought to interrupt a crappy electrical connection to the battery. Check and clean all battery, engine and chassis ground locations.
