Then it will start right up and run for 45 seconds and do the same thing.

Thanks for the in put that's all good that was an issue prior but the engine cutting out after warming up was ECU related kinda. The ECU was cutting the engine off because of low oil pressure from a leaking oil pressure sending unit so thanks again for reaching out and giving your thoughts !!!! Bob Heck

make sure you have good water (engine coolant) flow through the regulator and back to the engine.

Fact of the week
Some trees retain a form of biological memory of past droughts, and after surviving a dry period can change how their stomata (tiny pores on leaves) regulate water, and adjust growth patterns for years afterward.
