rb20 running problems

I just put a rb20 in my coupe and it was running good for an hour so then out of no where it started to sputter like crazy and run rich. then when i turned it off it was now hard to get going again. I've been told things as maf vacuum leak somewhere or faulty injector maybe. But if it was something fuel related that was faulty wouldn't it have been doing that from the start? someone please help.

Probably temp related, which in return controls fuel. So no you wouldn't notice from the start! Don't hesitate to check everythang, everythang that's right everythang; look out for your star player pimpin!

couple things. important things. please check

1) did you tighten your CAS. ive done it.
2) do you have ample chassis - engine grounds and are they tight . done this too.
3)your engine wouldve heated up in an hour. doubt its coolant temp sensor..
4) when does it sputter. exactly.
