A few weeks back I was dealing with a starting issue I assumed had to do with the key.
I got that sorted and the car started perfectly fine. Since then I’ve started it periodically. Today I my other car went down and I needed to drive my Gs400 and when I started it to warm it up it just died all of a sudden. After it shut off i tried to start it but got nothing. Tried again and the car wasn’t even on as if it didn’t have a battery. The security light is off completely. And I’m not sure what is going on. I looked before I made this but nothing seemed to match up to what I’m getting. Before the car wouldn’t start but the security light would continue to blink indicating there was a problem with the key. Now it’s not on at all so I don’t know what happened.

When you say it started to warm up how long was the car running before it shut off?

Less than 5 minutes

How many miles are on the vehicle? If it starts that would rule out your battery although your alternator might not be charging it. Any auto store can check your charging system for free. However, since you mentioned it ran ok for 5 minutes that sounds like a fuel issue, maybe it's not getting the right pressure.

well I went to check it out this morning and it had no power. Unhooked the battery and hooked it back up I had power. But if I start it I think a light blinks and it just loses all power. After a while thevpower will return but it will not crank over. I’m going to recheck the fuses again to make sure I didn’t miss anything. Maybe a relay possibly??

First step is to check your battery and charging system. The battery should read 12.5v+ at rest. Start the car and the charging system should read 14v or so. You can pick up a cheap multimeter for $10 (see below). Which light is blinking, the battery light or check engine light?
