    My D90's shutter release sometimes stops working while in manual mode
    with an MF 100-300 zoom at f8 (internal focus, max f4 through range) in
    full daylight. I can take a few shots, then the shutter release stops
    working when pressed all the way down. Can get shots when camera points
    at the ground or sky (completely out of focus) or occasionally after
    zooming out. Can't tell for sure what makes it start working again,
    assume this is related to focus and the electronic rangefinder. Not
    using flash, have lots of room on SD card. Do I just have to live with
    this?

    Sounds like what might happen if the lens can't achieve focus and the camera
    is set to not let the shutter fire under that circumstance.

    Yup, that sounds like it. How do I tell the camera to allow shooting
    without focus confirmation?

    With my D300S that is done in the Custom Menu a1 & a2.

    The D90 is a little different as it doesn't have those options, so
    perhaps the following might help:
    Since you are shooting a manual focus lens, have you set the "Camera
    Focus-mode" on the front left of the D90 from "AF" to "M"?
    That should allow you to trip the shutter, even when not in focus. It
    is not just a case of selecting "M" mode from the "P", "S", "A", or "M"
    from the Mode dial on top of the D90. For full manual, both focus and
    exposure modes have to be set to "M".

    Hmm, tried that. Setting body to MF doesn't seem to make a difference.
    Will investigate further.

    Sounds like it might be losing electrical contact between the body and
    lens. I'd start by removing the lens and cleaning the contacts on
    both. How worn is the mounting flange on the lens? I've had similar
    issues on my 1st gen 70-200mm f/2.8 VR with a mount with increased
    slop in it due to wear.

    I had the ame issue with my 70-200 ist gen. I brought it into Nikon,
    repair, turned out to be a bent contact. I had dropped the lens. It ws
    not a cheap repair.
