I don't know if you made any progress with this yet or not, but the other posts are exactly right. Any air leak introduces excess unmetered air into the engine. The ECU will compensate some based on what the O2 sensor says the end result is, but assuming you've got a typical level of leakage at the intake, and assorted vacuum hoses, and then you throw a pretty significant leak from the air hose into the equation, you've got a pretty good source for your no-start condition.

To test this as the possible solution, try just wrapping that big hose in duct tape to seal it up. If that cures it, plan on getting a new one before too long. FCP Groton sells this:
Air Intake Hose B2000-27092 Scan-Tech Production $19.63
If nothign else this hose leaking will cause radical idle speed irregularities.
