Your post is hard to understand. You didn't use any punctuation and you didn't describe the problem. Does it happen when the engine is hot or cold. Does it feel like just one cylinder is misfiring, or all of them? How long does the misfire happen? Just one engine revolution or for 1/2 second? Does your dash gauges jump when it misfires?
First thing I would check is the rectangular plug on your ignition coil. They loosen up and crack over time, and the terminals fall out. Give the wires a gentle tug to see if they can easily be pulled out.Second thing I would suspect is your ignition switch. Play with your key while it's running, or reach under the dash and tug on the wiring harness in the steering column. The ignition switches are known to wear out or melt, leaving you with an 'ignition cut out event'.

So took a little time to drive and see more of what it’s doing and I know that I can drive it 20 min no issue let it set for an hour then when I go to drive again it start to randomly miss so seems like a issue when it’s warm and warmer outside temps I think makes it worse
