Bruce Jenner has stopped production of his docuseries chronicling his transformation from a man into a woman, because he feels pressured by producers and has concerns about his family.
Sources connected with the project tell TMZ ... Bruce told producers 2 weeks ago he felt like they were rushing him and compromising his family by gunning for a May air date.
Bruce has two big issues -- he wants to make sure his 3 sons are "in a good place" to handle the radical change he's undergoing. He realized the cart was driving the horse, and that the show cannot proceed until his kids are psychologically able to handle it.
We're also told the recent car crash -- in which a woman died as an apparent result of his inattentiveness -- has had such an emotional impact on him that he needs to deal with it before proceeding with the docuseries.
A source directly connected to the project told us ... "There's a 99.9% chance the docuseries will happen," but it's still possible Bruce could pull the plug. As we reported, Bunim/Murray Productions will produce the docuseries.
Our sources say there's almost no doubt it will air, but there's no way it will happen in May.
One project will NOT be delayed. We're told Bruce's interview with Diane Sawyer is proceeding on schedule. It's being shot in various locations with Bruce and is not affected by his family or the crash.
