Thanks for the input. The car has been well maintained with all the required items changed out when they should be. The car has 128k so things are beginning to wear out. I'm going to try replacing some of the various parts and see where it goes.

The issue only happens when it's hot so it may be the sensor you referenced. Any idea on the cost/trouble of replacing the sensor or main relay. I'm not much of a mechanic so if it's up there on the difficulty rating I'm going to be stuck heading to a mechanic.

Thanks again. First time on the site.
