my lesabre has same issue, while running it just stops, i have noticed that if traveling at higher speeds i can turn off and then back on and it will run fine, my car is giving me the code 42, and 44. 42 has to deal with ignition either grounded or wire may not have complete circuit (short), it also deals with fuel pump cutoff switch being shorted or grounded. .

this problem can exist due to faulty carburetor or faulty ignition plug.

I experienced a problem with a 84 Grand Marquis that would stall at stops. Found that the ignition switch in the steering column had separated that caused the stalling problem. Replaced the ignition switch that solved the problem.

Most likely a clogged fuel lie, filter, or obstruction at fuel pump in tank. Also check tank venting and cap that might create "vapor lock".
