I have had the spark plugs changed and the coils, it helped for a couple of months. Now it is starting to miss again. The check engine light flashes and a message Service Stabilitrak comes on. If I turn off the traction control it seems to miss less. I have had the spark plugs replaced and the coils.

It sounds like they may have cracked one of the spark plugs or you have a defective ignition coil, but to be sure we need to run the codes which should tell us which cylinder is having the issue. The Service Stabilitrak can come on when the engine is misfiring so lets handle that problem first. Here is a guide to help.
