Engine won't start and evrything is dark

[Jetjock]

Back in 2016, the starter interrupt relay started giving me fits by not letting me start after driving a little bit. I replaced the relay and never had a problem with that. Last week or so, I took the car to car wash and after driving out, I shut down the engine and cleaned up the car inside and out. When I was done, it wouldn't start. Same scenario. Called AAA and got the car home and then it started. I went ahead and replaced the relay because it acted exactly like the last time that it did it. The guy at the parts store said that this was the right relay for the car so I got it and it started right up, no issues. I moved the car a few times since then with no problems. Yesterday, I started it up to go something and it did it again except this time everything went dark. I had instrumentation before and now nothing.



One note to mention. We did have thunderstorms pass through the area with high winds. The house is ok electrically except for the garage. All of the outlets are out including the one for the garage door. I checked the CB and it was fine. I rigged up a bypass so my wife can get in and out. The car was hooked up to the battery tender at the time of the storm. Its kinda weird for these things to happen like this. Any thoughts about the car?
