    91 seville cuts off

    My 91 seville cuts off usually shortly after i take off. drives fine after that. It does idle kinda rough now. but after leaving the ball park's parking lot, it cut off like 3 times , mostly when i slowed down. But again once i drive for a while on the street this doesnt happen. I will probable go to oreillys and get car checked for codes, meanwhile any suggestion on what this might be.

    Did you have history ECM codes? History codes are important with intermittent problems.
