but when he says he looses all elc power that screams battery will it start up if you let it cool down like for a couple of hrs or do you need to jump it?
your battery isnt holding a charge at all once you get the car started its running off the alt which also sounds like its getting tired
like many other have suggested take it to a local auto parts store that does testing and have it checked out

I'm going to jump in here and say that from what he has said, his alternator should be replaced. It might not fix all of the problems, but most of them will go away. I just had the SAME exact thing happen to my car. I knew right away that that was what it was. Didn't even check it. just got a new one, and boom. fixed the problem.
If you can drive it, and turn it off then right back on, but let it sit and it wont start, thats gonna be your alt. It will also affect your idle. When the alt dies, you are running straight off the battery, which I also suggest you replace, if it's not fairly new. If its not a new battery and you've been running around for a while like this, the battery is probably going to be so discharged that it will have developed "memory" and will not hold a charge.
Just my opinion based on what I went though only days ago.

Probably just like they say above.......battery or miserable charging problem. Low battery voltage will make the ECU act funny in a not too funny way. We still have not got a answer about what happens after you can't get it to even turn over. We're guessing you jumper it off. Seems you would get a meter out and when the car is running put the meter on the alternator output to see if it's charging or not and if it is.....check out the battery and replace it.
The idle should be addressed by the link pasted by NZConvertible.
But it seems your car has a trait that has not been addressed yet. You say not even the radio works when it won't start. We assume all the connectors on the battery have been looked at. But what can happen and has happen before, is the black wire that feeds the ignition from the 80amp fuse in the engine bay might be irregular. It's a black wire that is tee'd to the black wire that goes from the alternator to the 80 amp fuse.
There is a connector just below the fuse box in the engine bay. A single blade connector. If it's broken or half *** made....then there will be no juice from the battery to the ignition key. No juice on that wire when the alternator is not a pumpin results in no radio, no lights, not much of nothin. If that wire is the culprit, that would explain some of your problems. Not the rough idle though.
I'd post the schematic but it's toooooooooo much trouble on this site.

Next time you get no action from the radio, key to start etc, find this connector https://www.rx7club.com/attachment.p...postid=1352957
below you igintion switch by about a foot or so. Just the connector shown that has the large gauge BLACK wire. See if you have 12v on it. It should have 12v on it day and night key in/key out. No 12v equals a bad connection probable about a foot below the fuse box in the engine bay. The single blade connector mentioned in an above post.
