LT1 will start and die...is it IAC

i ahve check fuel pressure and its good, fuel pump is fine (dyno afr showed to be 13.0 - 12.0, so im not lean in any way)

i was told to check the IAC, i did, and then cleaned it with only a shop rag to get the tons of build-up off of it.,.....this fixed it for a few days, now its back....just wanted some advice from people who have had this prob b4 thanks
