I have a 1984 Stanza with EFI. Sometimes in cool weather, maybe 50F,
I'll start cold and drive half a mile to a store. When I crank up ten
minutes later and start to get underway, it may stall or nearly stall as
if not getting fuel.

So far it has always resumed running perfectly in a few seconds. Could
it be a temperature sensor? Could it leave me stranded?

Could it be that the engine has not sufficiently warmed up when you arrived
at the store?
Frequent short trips in cool weather without a fully warmed up engine can
cause the spark plugs to easily foul up with unburnt carbon deposits,
especially if the heat range is wrong.
Usually a longer drive (at least 5 miles) after a cold start can help
prevent fouled plugs.

I'm sure the engine isn't warmed up in half a mile, but wouldn't fouled
plugs make it hard to start cold? Wouldn't the response be weak or
rough when I stepped on the gas? This happens only for a moment. It's
sudden. Otherwise, the engine runs fine.
