My engine quit!

I was doing my BFR last night in my club's Piper Lance (in case you're not
familiar: it has retractable gear and a IO-540 fuel injected engine). We
finished up with a bunch of touch and goes, demonstrating short, soft,
etc. The last landing, the instructor pulled the throttle and had me do a
forced landing. I had no trouble making the runway, and rolled off the
runway and over the hold short line. As I was tuning the ground frequency
on the radio, the engine died. And I was unable to restart it and neither
was the instructor - I ended up having to call the FBO to tow me back to
the tie down line.

It wasn't until some hours later that it hit me - during the forced
approach, I had the throttle at idle, the mixture at rich and the boost
pump on. Which is exactly how you prime it for a cold start - except for
starting you only do it for about 3 seconds, and this was for the whole
duration of the forced approach. So I figure I probably flooded it. So
what's the answer? Do you turn off the boost pump when doing practice
forced approaches? What about normal approaches? Does that mean turning
on the boost pump has to become a normal action on go-arounds and touch
and goes?

Thanks for this one, Paul.
This situation hadn't occured to me, but it's one I could easily
encounter with either the Arrow or the Cherokee Six I fly.
Tip of the hat!

I can only speak for the Arrow. Checking the POH for our plane, it
calls for fuel pump on, and mixture "set". At my home field this means
mixture full rich.

I was taught "Pump, Red, Blue, Greens" (Fuel pump on, Mixture full Rich,
Prop full forward, 3 green landing gear indicators) call out on short
final. The only time I've hand any issue with this is at a high
altitude airport where I had the mixture too rich (wasn't full rich but
was rich enough that when I turned off at the taxiway, the engine quit).
