The car starts fine and drives fine for the first 10+ minutes until whatever is causing the issue, kicks in. I have noticed the issue only occurs when the car is hot. so if i was to cruise, the issue would take roughly 20 minutes to kick in, do some boosting and you will see the issue in 10 minutes. My Evo will randomly lose all power, not electricity but power in revs. I could put my foot flat in every gear and the revs wouldn't move up a mm, just revs drop to idle and car loses speed until she comes to a full stop then stalls. Once the issue has occurred, the car will start every time no issue but once it starts, she stalls straight away. wait 5 minutes or so, give her some gas as you crank it, she starts and has enough juice to drive for the next 5 minutes hoping home is within reach. Extra- today after changing the crankshaft sensor, test drove and issue occurred, was idling on the side of the road and the car fully turned off. it turned off really smooth that mates in the car thought i turned the key to turn the car off. really confused as i don't really understand what has enough power to turn the car off like that. The car is also misfiring when re applying gas, stalls when coming to a halt and engaging clutch going into neutral and check engine light flashes sometimes, majority of the time is WOT in 3rd or 4th.

PLEASE if anyone has any idea what the issue could be, don't be shy to post. i really need peoples opinion on what the issue could be. The car idles and drives fine until the issue occurs, and i believe it is getting the fuel and air it needs as afr reads fine and she drives and idles fine when cold.

I have done a compression test, all 4 came out mint and healthy. I have tried changing my cop with new coils and plugs, changed Cam angle sensor, had the TPS checked, double checked for boost leaks and just recently purchased and changed the Crankshaft sensor with a new one. None of these components improved the issue. It seems to be getting worse and worse (kicking in earlier and harder to start after the issue has occurred).

My next ideas were to change the fuel relay or intake air temp sensor. But any ideas that could be causing my issue and where to look next would be great. Please help!!
