IT may or it may not. I always like to check the codes regardless, as a clue may pop up to aid. Or completely throw you off track, lol. Since this problem isn't consistant completly with the hot weather, it may be a false assumption.
IF a pcm is not right, it can do different things that aren't right.
Now that you mention it, a plastic bag of ice cubes with a cloth wrapped around it would do a the cooling thing. Sometimes we use this method as a final confirmation after running through the trouble tree charts or if it is intermittant in nature.
IF there are two relays the same, you can try swapping them and watch for a failure of the other circuit.
IF all else fails and this remains intermittant, when you take it in to the shop, ask them if the service manager is willing to drive it as a personal car until the problem happens. I work in an independent shop and we frequently do this for customers in the intermittant situations. Saves the customer diagnosis money and the Boss gas money.
Pull the oil dipstick, and check for a higher level than normal, oil being thin or the presence of fuel. This may tip off to this being loss of spark as oppossed to fuel.
