Subject: Why is the coil being weird????

I have been tinkering with my coil for a while now and it has been acting weird since the day I built it. but it is just starting to get on my nerves.

So basically
When I run my coil at first if is good. producing 30" sparks lots of noise etc. 
But after about 5-6 seconds it just craps out. The spark gap stops making the normal loud spark gap sounds and it starts to make a really quick softer sound. Like the one the tv makes when there is no channel and just static. At the same time the sparks length drops to about 4". 
I turn it off. let it chill for like 30 seconds and then it does the same thing. If I turn it off and don't let it chill it just does it quicker. 
Very annoying. 
I am currently using 5 obits in parallel and 2 .005uf home made capacitors. The spark gap is 2 bolts less than 1/4" apart in a tube that is connected to the blowing end of a vacuum. The frequency is about 600kHz. 
Any ideas and help will be great.

Many thanks,
Jay Howson
