CHECK
First thing to try is new plugs...This has been a problem in the past on many occasions...also check your air filter and your airfilter box. If this is fine then wait till dark and take out a bottle of lightly soapy water and use a misting spray to see if perhaps the spark plug boots or wires are sparking and just keep spraying things till you find the problem area...it could many things at 5300ft. I suspect you will find it to be electrical and not fuel related unless you have changed fuel and it isn't as good as it should be...try running some fresh gas preferably Premium in it...is your automatic oiler adjusted right? or do you mix it yourself??? check that it is actually working when you twist the throttle an dthat you haven't changed the type of oil. Injector oil is different...and it is pretty picky if you put in the wrong oil or even change brands...
