I suppose the OP posted more than one version of the .ASC. I don't think it's worth pursuing any further, but the fact that it runs OK with the simple opamp suggests that there is a problem with the AD757 model.

Or it suggests that there is a problem with THAT circuit when combined with a very wide-bandwidth op-amp like the AD797 (not 757).

The simple circuits I tried for the AD797 ran OK.

The fact that your schematic changes things, is indeed disturbing.
