rb25 randomally stalls??

[skyline084]

Hey everybody,
i'll be driving down the road and my car will just stall at random. It usually happens during boost, but has happened while cruising in 3rd and 4th too.
I have no idea what it is?
It's weird because it will run great for a while, than it just starts crappin out.
I'll have to let it sit for a minute, turn it on, let it idle and than see if i can get it over 3k without it hesitating/sputtering.

rb25 is stock/ walbro fuel pump/ j60 maf

Is this a Skyline engine in a Skyline or swapped into another chassis. What modifications have been done to the engine or electronics? Is this a new thing or an ongoing problem? If it's new what notable event preceded the beginning of this behavior?

It's swapped into a 240.. but i found what's wrong. Nipple on knock sensor broke, so it wasn't plugged. I guess it screwed with the timing and fuel cause the car would fall on its face around 3-4k and i could smell fuel. Just rigged the sensor in place until my new one gets here.
