MY 89 240sx keeps stalling out

My 1989 240sx won't idle and keeps stalling out unless I give it gas. It has been sitting outside for a few months and now won't stay running. Once I take-off, it drives ok but once I stop, it stalls. I put dry gas in the gas tank but that didn't seem to help. Any ideas are greatly appreciated. Thanks all.

clogged fuel filter?

pull any trouble codes?
