My 2 cents worth is that it's most likely a sensor that malfunctions when
warmed up. Does it set any codes? Possible also to have a manifold leak that
is more pronounced when hot. Did you check the TSB's on HMA service?

Unfortunately no codes are being generated. I would have hoped there
were as it would make life a little easier.

I've checked the TSBs on fuel and rough idle but didn't see anything
that looked like it was this problem.
