It sounds like a low coolant thing, have you checked level in radiater as well as overflow tank? If there is air in the sytem I believe you have to bleed it out. Could also be t-stat getting stuck open smetimes I suppose . Just guessing :)

I would be happy to look into this for you. Please feel free to contact me privately with the last eight of your VIN for more assistance. Thank you in advance.

You have air trapped in the cooling system. There's a bleeder on the engine, right front, near the front head. Loosen it and bleed out air once the engine is at full operating temps. Check and adjust fluid level afterwards.
