Since this projector was discontinued 6 years ago, you bought it used. Which means that the lamp is most probably also quite used.
So...what you are describing sounds like a lamp that needs replacing. An aged lamp can do this, it will run for a brief period and shut down. It is to weak to maintain "fire".
Of course, it could be something else in the projector that is failing, such as the lamp ballast power supply. But the only way to test is to replace the lamp. I suspect that if it is the lamp and you replace it, you'll see a dramatic difference in the quality of the image. As lamps age, their output dims. At the end of a lamp's life you can expect to have lost at least 75% of the lamps brightness.
