This is a Lua script that provides all sorts of failure scenarios. It can be auto-loaded at start so you don't have to set up failures every time. It can be configured for many different behaviors and probabilities. I have it running all the time, so I always have to be vigilant to make sure I didn't forget things. Flying the simulator can degrade your real-life skills because there are no consequences for being lax. This can alleviate some of those tendencies. 
You can also assign buttons/keys to show the current failures (if you can't figure out what went wrong) and to reset them. Rename to .lua and follow instructions at the top.
