Default Lt1 service engine light coming on

My 1995 camaro z28 with a lt1 has a problem with the service engine soon light coming on. I go to take off and when it gets to 2500 rpm it starts cutting out. Then you have to pull over or slow down and the service engine light comes on. It will run good with the light on. I put 2 new o2 sensors on it and it still does the same thing. Any ideas as to what is going on.
Thank you, Tim

Check the stored codes. Sounds like a spark issue, maybe a bad optispark.
