Had this happen to a work truck, it would occasionally sound the alarms and die when taking a curve fast. Topping off the surge tank seemed to help until one day I could hardly drive the truck even with a full surge tank. I ended up replacing the sensor at the bottom of the surge tank, problem solved. You'll have to get the sensor from a dealer, the only place I could find it.

I replaced the complete tank on my 04 and friends 05. It was only $40.
Not that price anymore. ACDelco 15161670 GM. Got it from Amazon. Did a quick check. Part # is good for 2003 to 2009.

Help me understand something... doesn't hydraboost utilize the hydraulic pressure from the power steering pump to "boost" the brake pedal? Is there actually an accumulator somewhere that holds some pressure to aid in braking once the engine is off?

Yes, and yes--it holds some pressure both in case of the engine shutting off and in case of the power steering pump or its drive belt failing. The accumulator is sometimes incorporated as a part of the hydroboost brake booster unit itself, rather than being a physically separate component. It only provides emergency pressure for the brakes, not for the steering power assist.

Here's some more general information, perhaps more than you really wanted, on the system.

Information above is good no how Hydro Boost works. On GM Medium Duty Trucks there is a difference. A electric pump is used to provide boost when power steering pumps fails or engine is not running. Here is picture showing master cylinder and pump motor.
