sr20det random power loss when its warm

[wangan_cruiser]

so i just got my engine sr20det rebuild. it runs ok. problem shows up when it sometimes it gets warm then i would have a big power loss. when it happens i just pull over and turn off the engine and start it right back and the problem goes away. it feels like the car goes to limp mode
