Sounds like you're not getting spark.
-Faulty Spark plugs
-Battery

& YES YOU NEED A TUNE.
Stop trying different ROMs it is pointless unless if it is a ROM from someone with the same setup as yours.

Im 95% sure of that problem is on fuel delivery. (always have to leave 5% margin for possible strange things or changing conditions )
Okay,can be also example engine heat sensor or something like that....We will see

We talked yesterday with Bryan (Razorlab),and thought that testing injectors will be best move next. He sent me new rom for test with oem injectors with current mods.
I will tow car tomorrow to my shop/garage,and start figuring out this problem more.
There is too dark outside,and no tools or motivation

Okay,seems like problem is not injector/-s.
Car starts almost fine,but again when engine get normal working temperature,it will not start again. But now i get engine back running,keeping throttle on floor and start estimate 2secs. But idle is again bad,and engine will shut off,without throttle.
I think not,but i ask anyway.Can failed 3port boost solenoid cause this.
I just remember that couple days before problems started,solenoid kept sound couple times when car was stand still and idle. And it should not do that.

Seems also that engine temperature is OK. Evoscan shows right realistic engine temps,and it will be from that sensor.Right?
I think i have to start measure fuel pressure next. Can be failed fuel pressure regulator too.....Only god knows.

I'm not an expert, but if you've look at everything mechanical, it's gotta be how your ECU is set up then.

Car had been running fine until now. The ROM doesn't change. Mechanical things can.

It sounded like a bad crank sensor, but that would keep the car from turning on at all.

It could be the fuel pump. If the amperage increases when the car is hot, it might result in shutdown. That might also explain the crappy idle. I would start there with a low amp probe.

This is what the amperage should look like on the right. The left is a bad pump with shutoff condition constantly exhibited:

I have the stock pump from my Ralliart. If you want to give that a try, let me know. I will get a hold of it and send it to you.

This seems intresting. Always thought that pump even works or not.
This is why i automatically close that idea out off my head.
Big thanks to you! I will definetly try with new pump asap i find time for car.
