See if there's a code 14 or 15 in module 4.1. 14 & 15 are hi and low readings from the temp sensor in the waterpump. This goes back to what Dan mentioned about the ECM getting a faulty reading on water temp.
Yes, do pull the codes, but for some reason mine didn't throw a code. I think it was because mine was still sending some voltage, but not much. It showed like -15 degrees when I datalogged, which I guess the computer sees as a possibility. If it doesn't send any voltage then it would read -40 in the datalog, and I'm guessing then a code would be thrown.
If you happen to know anyone with a USB to ALDL cable you can borrow, borrow it, then download Tunerpro RT for free and use it for datalogging. It's fairly easy and free and by looking at what is being logged you could likely tell your problem.
But still, clean the junk out from in front of the radiator first.
