car still stalls - replaced bad tfi module

[87 GT MUSTANG]

still have the same problems, car stalled when i drove it today and it wouldn't start back up, checked to see if i had fuel pressure in my rails and it shot out 2 feet high of course. so it can't be a bad fuel pump, plus ford checked it out and said i have accurate fuel pressure, went out 15 minutes later and it started up fine. Gonna check my o2 sensors tommorow but i can't see how an o2 sensor will cause your car to stall out and then not start back up, maybe give you bad gas milage is about it.anyways any help would be greatly appreciated. this is really killing me, don't wanna have to bring it back in but i guess i might not have a choice.
