Car starts...and then turns itself off...

[JohnnyWas]

I just had a new block swapped into my LX (d16y7 auto.) Everything else is the same (heads, cranks, etc.) it's just a new block.

When we start it up, the car runs perfect for about 10min, and then out of nowhere, it turns itself off and won't start for another 10. It's perfect compression when it runs, and it runs smooth. But then out of the blue, it's as if someone just turned the key.


HELP! I need to know very soon what this may be...

probably forgot to hook something up. do you get a check engine light? try jumping the service jumperto check for codes. some codes can pop up but might not be enough to set the light off.

if you keep it throttled like 3-4k rpm will it die sooner? if so, fuel problem.

well actually, if i keep it up, it doesn't die. see, it's idling at 500-1k rpms, which is bad. that's when it stalls. what is it?

Not getting ENOUGH fuel? something shorting?
