Been using AFM M20R for a few of weeks without any problems, but I have been unable to start its engine this morning. I had the same problem on a cross-country stop a couple of days ago and had to restart via the menu; I'm sure that will probably work again, but would rather figure out what is going on. I've followed the checklists, double checked electrical and fuel supply, maintenance items...just can't seem to find a cause, any ideas?
