I've heard this also Jon and I guess I should have expanded on my
comment.
When you "run it till it dies" the truck is actually be fueled by the
contents of the cleaner can only. The stock fuel delivery system
supplies no additional fuel. When the can is empty of its cleaning
solution the vehicle simply quits running. You shut off the vehicle,
disconnect the can, reenable the fuel pump, and when you key on again
to restart the fuel pump reprimes the injectors and you should have
nice, clean injectors. Shadetree Mechanic actually did an episode on
this and I've seen the injector cleaning kits in the Summit catalog.
The one thing you have to remember when dealing with a fuel injected
vehicle is that the fuel system is under pressure. Disconnect
something without being prepared and you get a gasoline shower. I'm
no expert on this, only passing along some observed knowledge as all
my past vehicles have been carbs. I watched my brother do this once
(he used to be a mechanic) and it doesn't seem too difficult.

I could be wrong, but it is my understanding that letting a fuel
injected engine run out of fuel and stall is a bad thing(tm).
Several people on this list have said to be careful not to
run completely out of gas. (I forget why though, and I'm too tired
to look in the archives.) ;)
