You may be experiencing computer confusion as fuel supply sources are doing their seasonal switch over between winter and summer fuel formulations. Also - a post in another currently active thread reminded me that you may have water/moisture or other contamination in the fuel - usually fixed up by running thru a tank or two of fuel with Sea Foam or Techron additive in it.
If that's not it, you may have a failing engine sensor (cam position and crank position). I'd try Sea Foam or Techron first - good for cleaning out fuel injectors anyway, so that's a second benefit.
