ECU Code 15.....Ignition output signal

What are symptoms of a bad ignitor? Will it just shut off the car and fail to start for a while? My car was great........died..........replaced the whole dizzy........they (the shop) said it ran great......the day I picked it up it died 3 times.......but finally made it home.......now it's down to running for about 4 mins and just shuts off. The car will crank but won't turn over. New Battery, New Plugs, didn't put new wires, but just curious.

And I've been told everything here.....done the main relay, done the iacv (cleaned didn't work......disconnect and man idle didn't work), FITV didn't work.



Thanks in advance,
G
