Thanks Jim. The boat is in Idaho and I'm back in Colorado now. I'm hoping she will bring it into the MC or Cobalt dealer in the next week or so.
Rest time was anywhere from 30 min to 1 hour. I did try several methods.....give a little gas, give it no gas, give it a lot of gas.....still just didn't want to start all the way. It stumbled, runs rough, hear a backfire, and then stalls out. Lasts from 5-10 seconds before stalling again. Almost like a vapor lock, heat soak type of issue. If they find someting, I'll report back.
