I'm running my starter fertilizer through my new TMX this year.  Prior to this I was using an FMX and everything worked fine.  Thursday I went out to test things in the field (after testing them on the yard in diagnostics) and the starter wouldn't turn on or flush when a field was loaded.  It was windy and miserable so I went home.  In the shop everything worked fine through diagnostics.  After a call to my dealer (who admitted he'd seen a similar problem before) I learned that if I go through diagnostics immediately before opening the field everything will work fine.  If I change fields I must first open diagnostics again.  The config profile was imported directly from the FMX but the dealer said on his other problem machine they tried rebuilding it and it still caused a problem.  Has anyone else experienced this issue?
