Unfortunately the batteries in my crystal ball have failed so, based on the information you gave, you will not get a lot of help here.

It's a Mac?
The OS is ???
The applications, that you leave running without quitting them, are?

I have a 27" iMac running the latest software.

Mainly running iTunes, Song Genie, Cover Scout Dreamweaver, Safari, mail, Skype, and address book.

iPhoto VLC, and quicktime Pro are run occasionally. I can only regain the lost CPU usage by restarting.

At times it gets to 100% CPU between User and System. User is the larger with 90%.

One of your constantly on applications

has a memory leak.
This means that it asks for more and more of the available RAM until such time as there is no more to get. Then the system starts to behave erratically.

Suggestion:
The leak in Safari was fixed, so you should be looking at a process of elimination on the others.

Keep track of what you have running and note the RAM loss. Remove half the apps, after restarting, and see if the problem reappears.
If it does, take a look at the Activity Monitor, Applications folder, and see who is eating all the RAM.
Chances are that you are running something that needs an update.

Good luck

I have quit all Programs when the usage gets to 50%. Nothing is running.

I have just done a restart again and usage is now User/System 2/1% But it will creep up to 40-50% soon.

I use iStat Pro to check it out.

All programs are terminated but the usage of the CPU is high. I have to restart the System to free up the CPU again

according to istat the CPU use goes up User 90% and the system 8% with no programs running.

I quit all programs. At the moment it is running at 2/1%

According to Force Quit window nothing is running. Growl is quit Snitch is Quit and Tech tool is Quit. I even relaunch the finder it still has the CPU User/System.

At the moment it is running OK I will have to wait for it to do it again to try again to track it down.

So we are not talking about a memory problem

but a CPU usage problem?

With Safari open I have an iStat reading of:
User 1%
System 1%
Nice 0%
Idle 90%

If your user is at 90%, something is going on that ought not be. What version of iStat are you using?
