2009 stalling

I have the same problem as the older corollas stalling out for no reason on highway at slower speeds it's like it runs out of gas it stalls slowly and when you get it started seconds later after a few times it takes awhile to get to normal idle like its starved of gas.some one on here was saying that toyota had 26 complaints I'm sure its alot more but when you go to the dealer 2 days ago they told me they have no issues with corollas stalling so they don't know what this could be.hmmmmm someone isn't being honest the car has 25000 km so whats that 15000 miles and this the second major issue it also had a problem with the transmission down shifting issue and had to be reprogrammed.My other vechicle is a toyota two fj cruiser and its been great so I not a toyota hater I just won't them to stop lying and look into the problem .
