I would guess bees or pot bound, but it could also be over/under watering or
poor soil quality.

You shouldn't expect to have too much fruit from a plant that grows quite
large that you are keeping in a pot -regardless of how big the pot is

If the leaves are yellow looking you may have a soil difficency, which would
also lead to poor flowering/fruiting.

Are you feeding fertaliser it in this pot A LOT ?
I'd guess it would need it. How long has it been in the pot ? Are you
changing the soil in the pot yearly and replacing it with good organic
matter ?

All of these questions need to be addressed.
For best results plant the poor bugger in the ground.

Bees.
