I want to set my Scirocco on fire!

I posted before that my 87 8v Auto has been having some issues. The car will run for about 15-25 min then start to sputter and die. It will start right back up but will die quickly. So far I have replaced the transfer pump. main pump, fuel pump relay, coil and cleaned up the grounds and added a thicker ground from the valve cover to the firewall. I'm really not sure if this is a fuel issue or electrical.  The fuel pumps were used so I guess it possible that the transfer pump is bad which was what I first thought. Someone said it could be a distributor problem I'm going to try to swap that this week. Any other thoughts would be great.
