Plane was behaving abnormally in auto modes.(Log Attached)

Hi all, My Easystar-II with OmnibusF4ProV3 was behaving abnormally after i switched from FBWA to loiter and cruise mode.It was trying to stall.Then i landed it and took off again and all was fine after.Only thing i am suspecting moisture from the grass entering the pitot tube as grass was quite wet while taking off.I am attaching a log.Could anyone please have a look?Thanks.
