Hot Start: Challenger 650 - IRS Mid Flight Failure

[hockey4life74]

Was flying the CL650 from KSTL to KCVG tonight and about halfway through my flight all three of my IRS's stopped working. I wasn't touching my keyboard, mouse, or any peripherals when this happened. I don't have any idea what caused the error (I don't have random failures on in Xplane and as far as I know they aren't a part of the cl650 either) but I've attached my log.text file with all the logs I have from today.

Had this happen again tonight, I was not at my computer when the failure occurred so I can be sure it wasn't because of input from me. I also noticed a sizeable decrease in framerate after this happened. I believe it has to do with these lines here although I don't know what this API is.
