I doesn't appear that you've paid any attention to the motor contacts in the timer.

Sounds like something in the motor circuit is heating up due to a poor connection, it could be in the timer, but check thermal fuse and wire connections at the motor. Can anyone post a wiring diagram?
You've pretty much rolled out the motor it seems.
Check to make sure the door latch is not broken and letting the door pop open, (most likely not the problem but it has happened before).
Then check the door switch and timer contact points BK-Black to BU-Blue, if it's the timer it would have to be those contact points.
