Stop STALLING!!!!

clogged fuel filter?

what year is it? if it is an 87-90, then it is probably the ignition modual (TFI). When these moduals get hot, they tend to quit working, so leaving it in parking lot to heat soak, or while driving it, they are the most likely to quit.

Everynow and then I'll get a weird problem like that here at the dealership. Most of the time I cna't duplicate the problem since its intermitent.
For weird problems such as that Typically distributor parts....EI the aformentioned TFI module or the pick-up in the distributor. I had some problems with the 88 coupe and I replaced the EEC relay and never had another problem.

EIDT: Missed the part where you say its a 92. Sometimes the crankshaft sensor can cause some weird problems. For example. You migh thear the fuel pump prime for 2 seconds and the turn off when you turn the key on, but if its not seeing a signal that the crankshaft is turning it won't restart the fuel pump. Have somebody crank it over and try to listen for the fuel pump to turn back on after its cranking
