Thanks for all the valuable comments. I was briefly able to run some pressure tests on the motor this afternoon before having to leave the water.
It seems however that fuel rail pressure is not the culpeit. I have posted three videos.
1. Cold start (successful)
2. Hot start (successful) within about 10min of waeming up engine thoroughly at a range of throttle settings including some runs at WOT.
3. Hot start (unsuccessful) after sitting with motor stopped for 15min watching the rail pressure gradually bleed down to 20psi.
