My 93 940 turbo died while I was sitting at a stoplight this morning..it started up again and then died yet again...it started again and ran fine all the way home in city traffic. I'm wondering if I should be worried....car has 191,000 miles on it.
Seems to me you should pull the FPR and re-solder the connections. Common problem in 740/760/940.

Pull the fuel pump relay, pop the cover and have a look at the bottom of the circuit board, if the solder joints look cracked either fix those or replace the relay. There's a few other things that can cause stalling like that too, you definitely want that fixed or it could leave you stranded.
Mine did the same thing last week. Twice on the highway, once on a neighborhood street, and once at a stoplight. Each time the worknig period was about half of the previous working period.
I bought a new fuel pump relay ($50) and installed it. Piece of cake, the car hasn't stalled since, and only $50. Now that I have a working car, I will solder the old one and keep it for the time when the new one cracks.

That's right, Pierre, Fuel Pump Relay is a good culprit, a lesser known one is the Radio Suppression Relay, (which should have been called the Injector Power Relay).
All the best, Peter.
