I'm with Richmac on this. To the best of my knowledge, on these cars TRACS works by applying braking to the spinning wheel via the ABS system, not cutting power to the engine. So I suspect that your two problems are not actually related, I'm pretty confident that the TCV or something related to it is causing your engine to cut out, this absolutely ties in with the symptoms and there aren't many things that can cause the engine to cut without leaving a relevant code, and none that I can think of that would only happen under hard acceleration apart from TCV as described.

An interesting one - keep us updated!

Cheers
