Thanks, I didn't see a pattern before but the short drive, heat soak angle fits what I have been seeing. I'll probably get it taken care of tomorrow. Will report back as soon as I can say for sure that it was or wasn't the problem. I did notice that it takes longer for it to recover as the outside temps go up. No problem during the winter months and I have experienced this on and off for at least a couple of years. In hindsight it also cranks a little longer before it starts on warmer days lately where normally it will start as soon as the key is turned.
