We had this same recurring problem with this tahoe for the last 10k miles. Sometimes when driving at higher speed or just idling, it will display a "Reduced engine power" And you will loose all power.
Vehicle's autostop feature is extremely dangerous when driver is trying to apply the brakes and slow vehicle. Vehicle jolts violently forward upon breaking and accelerates to 10 mph.

Recalls for the 2008 Chevrolet Tahoe: 4
These vehicles are equipped with non-desiccated passenger frontal inflators containing phase-stabilized ammonium nitrate (PSAN) propellant. These inflators may explode due to propellant degradation occurring after long-term exposure to high absolute humidity, high temperatures, and high temperature cycling. An inflator explosion may result in sharp metal fragments striking the driver or other occupants, resulting in serious injury or death.

However, there have been new reports of thermal incidents on hwfs modules after this improvement was installed. These incidents resulted from a new failure mode attributed to the device's thermal protection feature. It is possible for the heated washer module to ignite and a fire may occur.
A short circuit on the printed circuit board for the washer fluid heater may overheat the control-circuit ground wire. This may cause other electrical features to malfunction, create an odor, or cause smoke increasing the risk of a fire.
A recall may cover only some cars of a model year; the campaign size counts every model and year it lists. Enter your VIN at nhtsa.gov/recalls: dealers fix open recalls free.
