92 shuts off when it warm up

92 4dr gs auto..... just started shutting down ... it's starts fine but shut's off after a little while.........there is a little ( very little) sputter then it goes dead.... i recentlly used an injector cleaner would this have affected something??? I'm thinking it could be the ignition coil but i changed that last year... any help appreciated

well i got a sugestion to change the fuel filter as it's not been done and it did seem to be starved a bit but ... today it cut out again... after 10 minutes it started right up.... anyone have any thought's???????????????

ok so i read some more posts and i'v done the self diagnostic ... it comes up 15 which indicateds IGNITION OUTPUT SIGNAL??????? ... So what am i dealing with here any sugestions would be appreciated

ok so changed the main relay and got about 15klm( 10 miles) befor it shut down again.......... so it looks like that's not the problem ...can anyone tell me if the distributer is supposed to be hot to the touch????

well after the overwhelming response (???) I swapped out first the coil then the ignighter... It appeares that the ignighter was the problem.. if it dosent cut out tomorrow i should be home free till the next mishap.... thanks for your support
