engine stalls and won't restart when warm

Fuel System

Model: 911, Year:1972, Mileage:125000, Type of use:Street use only
Hello Ed,I have a 2.4 MFI car and drive it only in summer months that I have owned for 3 years.Last fall my car developed a fuel pump leak so I replaced it with another one that had the same part # and looked identical. I then discoved some fuel line leaks near the pump so I replaced those as well. I then stored the car over the winter in my insulated garage with a full tank of gas with fuel stabalizer and a trickle charger (like I do every year)Yesterday I started the car for the first time this year and she fired up right away with a bit of throttle. After warm up I went for a ride and after about 10 minutes it started to sputter and bog down and quickly stalled. It would not start so I had to get it towed back home (10 kms) This morning she started up the same way and sounded fine with no problems reving freely up to any rpm. Then after about 10-15 minutes she stalled. I started her back up and again and had same problem with a bit of backfiring, lack of power and finally she stalled. Not able to restart.I will admit that I am not that mechanically inclined but try to do as much as I can myself as I enjoy tinkering with the car. Also, I don't have any special tools to measure fuel pressure etc.I would appreciate any help you could offer and I respect all the work that you do for the club. Thank you in advance.Joe.
