If the engine quits on you while in flight and you don't have any indications of fire, this is the checklist for you. There is also Engine Failure Above V1 to consider. That checklist gets you away from the ground before considering many of the items shown here. (You don't have to do this checklist if you've done that checklist.) What makes this checklist different is that it also mentions drift down.
Keep in mind that a red Eng Out (U) CAS message tells you a relight is possible, while a red Eng Fail (U) message tells you a relight should not be attempted.
Everything here is from the references shown below, with a few comments in an alternate color.
Auto Speeds will update to single engine drift down airspeed.
Autothrottles must remain off to maintain drift down descent profile.
(1) ALT HOLD . . . Select
(2) MAN SPEED . . . Select
(3) Single Engine Cruise Speed (TSC/FMS/Perf Init/POF Data) . . . Set in SPEED window
(4) Autothrottle . . . As desired.
The APU may be used as an alternate source of electrical power. Refer to 03-03-10, APU Inflight Operation - Alternate Electrical Power Source.
Be careful! If you are already in icing conditions with an engine shut down and then, even momentarily, turn the wing anti-ice off, you have just 60 seconds to turn it back off before you are locked into a Stall Ref Speed Increase situation. This happens because the AOA protection system assumes wings are contaminated and reduces AOA to prevent stall, and that will require you to increase VREF by 20% and landing distance by 50%. I heard from a Gulfstream flight controls engineer that if you don't get the wing anti-ice back on in 60 seconds, you will not have the chance again. If you are in icing conditions and the wing anti-ice is already hard selected ON, leave it there.
WAI MUST BE ACTIVATED AND REACH AN OPERATING TEMPERATURE GREATER THAN 100°F PRIOR TO ENTRY INTO ICING CONDITIONS.
Do not attempt an airstart if an Eng Fail (warning) CAS message was displayed prior to the Fuel Control being shut off.
