Intermittent problems can be hard to track down. You need to rule out something. Are there any codes? Is the fuel pressure ok? How long since it had a tune-up?

Usually on something like this, the first thing I think about is, maybe your losing the rpm signal, intemittently? I couldn't be sure without trying some testing.
