Take a picture or something, this shit sounds confusing as hell. You don't really give us any info as to why it would do it in the first place. Clearly, it's an issue with your wheel or bearings. Cause I highly doubt you bent the fork.
And it makes no sense that you ride fine, then your wheel just suddenly stops when you land an air out. Because if that were the case, you wouldn't have gotten rolling in the first place.
