CAR STALLS WHEN WARMED UP.

1993 Honda Civic • 173,000 miles

Car won't start sometimes when warmed up. When I get it started I smell a lot of fuel. Seems to be getting to rich of a mixture. What possible causes could it be? The inside of tailpipe is all sooty and black.
Replaced IAC replace PCV valve, took out main relay and re-soldered board. When it sits for about five or ten minutes I have problems. But when it sits for an 2 hours or more it starts fine. Is it possible that one or more of the fuel injectors is leaking fuel into the cylinders after the engine is shut off?

Yes, or while it is running. You need to insert a pressure gauge and watch the pressure at rest as well as running.
