I hooked up a smoke machine to the airbox (engine off) and pumped in smoke hoping to find a vacuum leak but no smoke escaped. I repeated the same process with the throttle wide open and no apparent leak.

I repeated the above AFTER the engine was run to full temperature since that's when the re-starting failure happens. I was hoping that maybe something like a clamp, boot or hose is expanding with the heat and creating an air leak. Needless to say, no smoke escaped.

I'm completely stumped.
