Usually something getting wet. Check the coils.

Any DTC codes with a OBD2 scanner ? Also check to see if a plug wire is resting on the headers and burning the wire. Sounds like you just installed headers ???

No the headers were recently installed by the previous owner. Codes were

P1133 Bank 1 Fuel Control Shifted Lean

And

P0300 Random Misfire Detected

Check sensors running to your engine. IAT, ETC, MAP etc. Had the same problem a couple months back on my SS and it ended being my ETC sensor (Engine Coolant Temperature) had rotted out and was gone. $15 part at oreilys and litterally took me all of 2 minutes to change it. All codes went off and car ran much better! Hope this helps.
