Help warm engine no start

Ok.....don't read my profile cause you will laugh!
1992 3.1 v-6 when engine is warm the car will stall and won't restart. The only way to get it started is to pour gass in the intake. Don't ask how I get the gas in there but I do. The engine will then start but will only stay running if I keep the RPM above 1500.
Now it has 48 lbs. of fuel pressure and the filter is new. Iit will run at 70 mph at 2250RPM all day but when you stop at a light it stalls. Any Ideas?

could be IAC motor, could just need an induction service.

Uh...what is an IAC motor let alone an induction service? I am not trying to be a smart ASSCI but see my post ( Fuel problems after engine warms up ) as I am having the same problems and was told my injectors were shorting out. I am still trying to find an answer.

Thank you
