After a water intrusion incident, it will take 2 or 3 oil changes to completely clear it out. Just use the cheapest oil you can find for the first 2 changes, as you're only going to be running it a...

Bad coil?

Next time it quits, immediatly check for spark while its in the "no start" time. A missing or weak yellow spark means a bad coil. Replace it with a new MMI unit.
