For the re-start trouble, look into "Evap Purge Valve". It's a valve under the left side intake. Here's an article on the basics (not Porsche, but similar): https://www.samarins.com/glossary/purge-valve.html
It may not be the cause of the P1128/1130, but it is likely still part of the problem.

Here's one discussion here: http://986forum.com/forums/performance-technical-chat/50264-success-finally-fixed-hard-start-while-hot-fueling-issues.html
