Try adjusting your front derailleur properly. Another thing to look at is how much dirt and gunk may be in the derailleur. After longer rides I need to clean mine because it picks up road dirt and overspill from the front bottle...like if you use sugar drinks and the drip only picks up more dirt which will impede shifting.
Look beyond the obvious...
