Urgent problem!

Hello all,
I have 150W of MH lighting over my 29g reef currently and today it has been randomly shutting off (like once every 1-2 hours). The current is still running to the system as the in unit fan still runs even though the light cuts out, and if I shut off the power to the system for 2-5 min the light will start up again when I power it back up. I have narrowed it down to a few possiblities and would like some general input as I have never seen a 'bad' ballast a 'bad' bulb or a power issues effect on MH lighting systems.
1.) bad wiring or power fluctuations due to weather (water has shut off a few times, and tv has flickered with power cuts) trips the bulb and causes it to shut off (its on a power strip with surge protection). I noticed one day when my timer was set poorly that if the unit shuts down and then is reactivated quickly the light will not come back on without a cooldown period. So if the power were rapidly cut it could cause this to appear like a blown bulb.
2.) bad bulb... I don't know what a MH bulb does when it 'goes bad' but hopefully someone here can tell me if it does anything like I'm describing.
3.) bad ballast... I am still under warrenty for my system/ballast so this wouldn't be horrible aside from the possiblity of having to go without lighting while the company asks me to jump through hoops to get a new one/get this one fixed.
I hope some experts out there can give me some insight so I don't end up wasting money on a new unecessary bulb.
thanks in advance for the help

There is also a very good possibility that this is your bulb as well, though I agree with sign guy that the ballast is the most likely culprit, most likely the capacitor in your ballast.
I'd contact your manufacturer and let them determine the best course of action, but act quickly, because if it is the ballast, it may destroy your bulb.
Incidentally, don't consider a replacement bulb a waste of money. It's always good to have a spare around. Halides can fail very suddenly or even explode if they get splashed while hot, and a spare can come in VERY handy at times like these...
