Any skill-based RP such as that is incredibly time consuming - both for the players and for the one running it. Furthermore, any individual running one must be both competant, and trusted not to abuse the OOC knowledge (e.g. Skill values) gained. The last attempt failed because the one running it no longer had the time. This is likely to be a common issue.
