I STFAd and did not find anything definitive. I replaced the OEM battery in September with a Sears DieHard International. This evening after work I went to start the car and it cranked twice then went to turn over but started cranking again so I went to let go of the key and the car turned over...but weakly. The car sat in the lot for 8 hours in about 25 degree temps so it was butt cold. I had this problem a couple weeks ago but the car was about 25% warmed up. Both times the car started but did not start up as usual.

So I know it is not the battery, I've seen people mention the coolant temp sensor, any other suggestions/ideas?

Dirty battery terminals? Low battery water?

Defective battery (yes, it happens)? short in the electrical system? Something electronics draining?

Hard to say what is exactly happening here but you may want to also have a shop check out your ignition switch. The electrical portion of the switch is plastic and wears out. Just a thought.

Good Luck
