I know, I know - just replace it. I probably will long-term. However, I want to get this 39,000 original mile Dippy on the road like, NOW. It'll run beautifully for 10-15 minutes. Starts like a dream. Once she warms up, it'll start to run rough and then stall. Shut it off and fire up again, and its the same thing. Runs great for 10-15 minutes. This thing is sooo clean, and the air cleaner has a tag on the computer that says reconditioned with a 2015 date. Where should I look first? I'm convinced it's a sensor or switch.
