I have had several WUs stop processing and never finish.
No error messages show up.
Other WUs run to 100% and are transferred.
This is the last message on the WU.

"State Waiting to run": There is no problem - just another task runs at the moment (High priority) and this task will be resumed (hours/days) later.
You Aborted a task after more than 17 hours of computation!:
http://einsteinathome.org/host/3256335/tasks&offset=0&show_names=0&state=5
Why?!
It is absolutely normal that some tasks will be paused ("Waiting to run") automatically by BOINC
and after some time resumed to continue the computation (from the % already done).
This is done by BOINC if it sees that some other task can miss the deadline
and so the current task is paused, another ("High priority" = may miss the deadline) tasks are done,
then the task is resumed when BOINC sees the time is appropriate.
P.S.
Just for testing purposes (no need/not recommended to do this regularly)
you can force BOINC to continue the task which is in state "Waiting to run":
Suspend all tasks but the one you want to run (to resume/start):
Select all tasks (click on any task, [Home], [Shift]-[End])
Un-Select the task you want to resume ([Ctrl]-click on it)
Press [Suspend] button at the left.
(of course you have to [Resume] the same way all the suspended tasks after the "wanted" task is finished)

I have suspended all other tasks and this task will get no further than 90.288% even after hours of running.

Did you try a reboot?

Yes I did reboot. That did not get the WU restarted.
All is working now.
I shut down all possible applications and eventually the WU did complete.
Thanks for the help.
RE: I shut down all

Is it possible that the WU was "waiting for memory"? From your first post:

I think "waiting for memory"
)
I think "waiting for memory" will be shown as State of the task.
Also even if you free memory by exiting unneeded programs this will not make the task run.
The way to give more memory is to change the BOINC Preferences
Memory: when computer is in use, use at most 70% of total
Memory: when computer is not in use, use at most 80% of total
(With Memory 750.8 MB try at least 50%)
Maybe the problem is this preference?:
Suspend work if CPU usage is above --- %
(change it to 0 (zero) to switch if off)

RE: Also even if you free
)
Why not? I think that would be the primary function of the client in this respect.

Usually only a few MB of RAM
)
Usually only a few MB of RAM are really free.
If BOINC checks for free RAM it will (almost) never run any app.
If you tell BOINC that it can use up to 50% of 1 GB RAM (= 500 MB)
BOINC will allocate the needed RAM (e.g. 200 MB) even if the OS reports only 1 MB of free RAM
(Windows will lower the RAM used for disk cache and swap to disk some parts of used RAM (used by idle programs) to free 200 MB RAM)
You can check this - set BOINC to use only 1% of RAM and it will wait for memory even if you exit all unneeded programs and OS reports 100s of MB of RAM free.
