Hey y'all! About an hour ago I was parked at Jackson Hole Airport in Wyoming ready to take off to Utah, and I did everything on the checklist and started the engine up. All was fine for a few seconds but then the engine turned off. I kept trying to turn it on, but the oil and fuel pressure would drop and it would turn back off  . I use real-world weather and I noticed that the barometric pressure was really high; about 30.40 inches Hg so I turned the real world off and switched to user-made weather.  All is well now and I managed to take off and is currently in flight. I think this may of been the problem but I'm not sure. (Engine failure was not scheduled either)

Question #2: I was cleared to land at Jackson Hole earlier and the ATC said "Mooney N20TMB cleared to land runway 34 closed traffic." Does anyone know what "closed traffic" means, because I don't remember ATC telling me anything like that before. But I am assuming that the airport is closed?  ???

Question #3: I set my settings for the aircraft to be completly shut down with everything off at the start of the flight. Is there anyway to turn it back to normal (default)?

I'm sorry for such a long post   and I gladly appreciate anyone who has any suggestions  

On the first question. If you are using a recip plane then what you need to do if the pressure jumps up is to lean the fuel mixture. You have to rember the altitude at jackson hole is 5,000 feet or so already so any jump in pressure would put you around 10,000 feet or higher. Proper procedure on recip aircraft is to lean the mixture as you gain altitude. With the mixtures set at rich your engine is starving for oxygen.
