How many petals do the flowers have? And the stamens?
Looks similar to the Sagittaria family which is a water plantain.
If it is in the bindweed family maybe it is a cuscuta or a dodder:

I wonder if something about pumpkins makes those plants behave differently? Or it might just be a different plant. Can you get a closer picture of the flower? That can really help with identification.
Of course! I love a good plant mystery. Hope you figure it out and it's not one of the more poorly behaved bindweed family members!
