While driving the car it will randomly stop accelerating, will lose all engine power and will die even when trying to give it gas but will start back up it seems to only do it after the car is warmed up. I have an Evo 9 that has been tuned by English racing on speed density and have already replaced the TPS and Coolant temp sensor but without luck I have been doing a good amount of research but can't seem to find a solid answer after data logging the car on evo scan the only thing that seems wrong is that the O2 sensors are weak and need to be replaced but I can't imagine that is causing the car to die? any help would be highly appreciated thank you

Did it start doing this after the tune? Could it be the speed density sensor?

I bought the car already tuned and it never did this until just recently and I have checked the speed density sensor it is clean and is reading correctly according to evo scan
