I'm thinking of something like 2nd and 9 or so after you got stuffed running up the middle. The other team still overwhelmingly will be trying to stop the run so running play action and a short pass would both be very likely to work and be very likely to get you the first down or close.
I've often thought about this, too. It's one of those decisions where coaches seem more worried about the consequences (and public backlash) of failure than the EV of the call.
In the vast majority of cases though, I think running is best. It's easy to say "they'll be selling out out against the run, play action would be money here", but certain run blitzes can still blow it up, and the execution rate is lower than you're giving credit IMO (you often see even the safest of passes get botched in one way or another). Plus, all it takes is one suspicious defender with the right hunch to make things go way way bad.
It's obviously extremely situation-dependent (score, time, opposing team's timeouts, their offense's hurry-up ability, etc.), and the occasional pass also has some meta-game value, but I think it's usually -EV in late game spots like that.
And even when the defense does know the run is coming, you'll still see the RB bust one through a lot of the time.

I think in this spot you can run more time off on average by passing.
A couple seconds maybe. Not significant enough to sway the decision in all but the rarest of spots.

That doesn't necessarily mean that it's always optimal but I suspect if somebody took a good look at it teams should be passing a lot more with the lead when their opponents are all out to stop the run.
I'm pretty sure I just disagree. When the clock is ticking, the trailing team doesn't have any timeouts, their defense is tired, the coaches are already trying to calculate whether they'll get the ball back with 50 seconds or a minute inside their own 30 IF they can stop the run 3 straight times, I bet they'd LOVE the team with the ball to try a pass with 2:20 on the clock.
