Guys im at the end of my wits with this one

Evo 7 will start and run for 5-20 so seconds then stops, try to restart it and it will fire and die

Leave it sitting for 10 mins and start it up it will run for 5-20 seconds then die and the process repeats ie leave it sit and it will fire and run

Parts ive swapped over to eliminate issue
Airflow meter
Cam angle sensor
Fuel pump relays 1,2,3
New spark plugs
Checked fuel pump operation
Checked compression all at 180psi
New battery

Car initially came in for new wastegate actuator, Ive touched nothing else

Any help would be awesome!!

Right i tried new leads, coil, fuel pump with no luck

Fuel pump continues to run when car stops, then turns off as it should, so not a fuel pump or delivery issue.

Funny thing is i started it from cold and it run for a couple of minutes, then died, then wont start unless you leave it for a few minutes and runs for 20 odd seconds then dies etc etc

So seems to be when it gets to operating temp?

Are plugs getting fuel fouled?

Does it stay started if open throttle?

No plugs are not fouling

No it won't keep running with throttle, it stops suddenly, doesn't splutter or cough etc just stops
