A vapor lock issue?, Starting after 30 minutes or so of sitting Options

[boxsterfan]

So on my 74 2.0L D-Jet, my car normally behaves this way on cold start:

1. Starts right up and idles high while cold
2. As it gets warmed up, the idle "hunts" between 0 RPM and 1200 RPM and can occasionally die when pulling up to a stop sign (you might have to blip the throttle).
3. After she warms up, she idles perfect at 900-950 RPM.

The problem:

1. Car is warmed up driving to a store (idling perfect 900-950 RPM)
2. Go into store for 30 minutes
3. Start car (starts for a second but then dies if you didn't give it any gas)
4. Turn key off
5. Turn key right back on and it doesn't want to start (just cranks). But if you give it gas while cranking you can get her to start....almost like push starting the motor and popping clutch).

Note: My fuel pump is in the front. Stainless steel lines in the tunnel.

Am I still experience vapor lock?

If it's flooding and it starts by holding pedal to floor, you likely have a leaking injector.
