Well, push come to shove, I'd have to say it's the self proclaimed expert on everything who compares himself to Jesus and blames the OP who asked if gas loses octane over time for causing him to expose his "A-holiness".
The OP didn't mention any CEL or codes. I'm an admitted rookie taking shots in the dark here but I'm betting on bad fuel or fuel pump with the most likely culprit being the fuel as others have said. I'd start with the easiest/cheapest. Check the spark plugs and gas. If there isn't too much gas in the tank I'd siphon off most of it and try putting some octane booster/injector and fuel system cleaner in the tank with some fresh 93 octane gas, and if it will run as long as you give it some gas pedal, run it a while to get the booster/cleaner and fresh fuel into the fuel system to see if that resolves the problem. If there is too much gas to siphon off,(where to put it if you don't have 4 five gallon cans?) same prescription without siphoning but use more octane booster?
