You say the lamp went out and the machine stopped. The key here is did the machine stop on its own? If so, you likely have a problem with the failsafe since it will stop the projector. If the projector stops, it will tell the lamphouse to turn off.
When the lamp turns off...do the blowers also shut down or does just the lamp turn off? The key to troubleshooting this is to find out what causes what to happen. If the installer followed the factory suggested wiring, then the projector tells the lamphouse/rectifier to turn on.
The Rectifier contactor switch leg is on the 122 and 122A (when 122 is connected to 122A, the rectifier is told to turn on).
The Lamphouse is on the 60A and 60B lines. When 60A is connected to 60B, the lamphouse is told to turn on the lamp.
Both the 122/122A and 60A/60B must connected for the lamp to turn on. In the projector, this is done by Relay re1a (one set of contacts is the 122/122A, the other is for 60A/60B).
Remember, there are lethal voltages present on all of those cables and in and around both the lamphouse and projector....don't poke and prod if you don't have a full understanding of what you are working on.
Again, if the projector is stopping as well, then the problem is likely with some sort of failsafe or perhaps re2 which forms the latch circuit to keep the projector running.

This all comes back to what exactly occurs during the failure...that is, if the projector turned off of its own accord then it isn't likely the sail switch (SK5) is the culprit which jumping 122 to 122A will bypass around.
Key things to note are...do the blowers shut off when the lamp is lit now? Is the hour meter advancing accurately.
As I said, there are two paths that need to be satisfied for the lamp to stay lit...one is for the lamphouse, one is for the rectifier.
If the blowers continue to operate normally (turn on when the projector starts, stay on until the lamp is cool) then John hit the nail on the head. If the blowers come on and off or the hour meter is losing time, your gremlin still exists.
Alternately, the relay or related wiring between the lamphouse and projector on the 122/122A circuit may also have an issue and jumping it out in the lamphouse is effectively bypassing it.
With 122/122A jumped, there will be no way to turn off the lamp, including if the lamphouse door is removed, unless you have a separate switch on the rectifier that will break the circuit too (Christie and IREM have such switches...Christies normally are active,...I've found about 50/50 on IREMs if the installer used them...I could see arguements both ways).
Good luck and keep us posted.
