Landed for refueling after a half-hour flight in 90deg weather. Fueling took about 20 minutes and the plane was pointed away from the wind. Sumped tanks, no contamination. Shortly after restart, the engine ran slightly rough and the only instrument indication was flickering of the RPM gauge (GRT EFIS). The engine smoothed out after about 15 seconds, and run-up was normal, so I flew home (30 mins) uneventfully.
What would cause this, and is it something to worry about?
