By the time one is aware things like Immodium might be in order, it is usually too late... consider declaring a Mayday, perhaps...
Seriously though: anyone who spends the amount of money required to keep a certified plane flying is a fool to rely on "consumer grade" pseudo-avionics. It must all be on the same line of cost/reliability: either you go for certified but then you go for certified avionics too; or you fly on a PtF and you concoct what you can - AND have your plan B for the day your concoction suddenly stops.
Myself in the second category, I have survived a couple of sudden stops. Combination of good luck and good plan B, up till now. Fingers crossed for tomorrow.
