If you mean it is turning over OK, but doesn't want to fire, that has been discussed here. Do a search and you will see. I tried, but my search skills are obviously no good. I get x thousands of answers!??
Basically it is a heat problem "fooling" the ecu to be extra rich.

Old school, what do you mean by hard to start?
Does the starter turn slowly or not at all like the typical 'hot start' problem or does the engine turn over at the normal speed but doesn't fire? I am sure the FI gurus can pitch in on this one
Some year models you're supposed to gie ut gas when starting, IIRC
I never had that happen before, It always would fire right up.

Jaimie - the owners' manual says to put the pedal to the floor & hold it while cranking until the motor catches (or a reasonable time cranking then retry) & release after started. That's D-jet SOP per Porsche.
If your fuel pump is still in the rear/engine compartment, then it's well worthwhile to get the reloc. kit (AA & ??) & move it up in the notch behind the steering rack cover per the factory service bulletin. I had mine done back in 78 after sitting it out at the Blythe Denny's coming back from summer water skiing, & no vapor lock problems after that!

So you're a believer in the vapor lock issue + fix? My car stalled this summer on a hot day, but there appears to be some debate on these forums about whether vapor lock is a real issue or not. I'm not sure what to believe at this point.

I have the exact same symptom as you... Get in in the morning and it fires right up. Motor 10 minutes down the road to the gas station, shut it down, fule up and it cranks over hard and fast for 30-45 seconds then slowly comes to life. Then it runs but wants to die for about 2-3 minutes.
I have my fuel pump in the front and that didn't help, but today when I fueled up I pressed the gas pedal to the floor and held it before I started cranking the motor and it fired up just like it does cold.

Your reasoning is unclear, and your conclusion is unsupported and false.
