Hesitation/Stall question

Hey all after along time coming I have finally been taking the Duster for some test drives and enjoying it. But I have been running into some small issues it started with what I though and still could be a fuel issue.
The motor is a 318 bored .30 over with a 0 deck height with the 302 heads, Comp Cam XE268H, Edelbrock RPM intake with an Edelbrock 1405 carb.
Today I took it out on a good distance drive hit WOT a few times and driving it nice the rest of the time. When coming to a stop I pop it in neutral because it wants to drop the RPMs to low and try to stall. The Transmission is a 904 rebuilt by a local shop with a OEM stall converter. When I got home I was pulling in the driveway and wasn't touching the gas the car died. Fired right back up and pulled up the drive and did the same in the garage. After I parked it I looked at the fuel filter and it pretty much was empty. Is that to be expected?

Typically I would assume the stall converter is the issue since it will try to die as soon as I drop it in reverse or drive and give it no gas. But I have had it stall out and not want to start again after stalling for about 10 minutes of trying to turn it over almost like it is starving for fuel.

Has anyone experience anything like this running an OEM fuel pump with the setup above?
I purchased the Edelbrock Performance pump that is self regulated at 5 or 6 psi, just haven't installed it yet. I am thinking that if my cam is suggesting that a 2000 stall works best this could be the issue, not high enough RPMS when in gear and idling to pump up enough fuel maybe?
Just not sure if I am on the right path.
