This is a 4.8 litre vortec engine. It runs for about 5 min. And then just quits without stumbling. Stops dead. Then just cranks and will not start. Plus no spark
After a while it will start and do the same thing. Quit and no spark.
I doubt all the coil packs have failed together and then come back together.
What could be causing this?
