So i thought I had the problem fixed but apparently not. Put a new coil in the car and all has been well. Until recently , now the car every once in a while will still shut itself off however sometimes the RPM's will shoot up for a second before the car shuts off. Sometimes you have to wait it out for the car to restart, sometimes it i will immediately start right back up and you can continue driving basically till you get where you are going without issue???? Today I heard what sounded like a very noticeable rumble from the rear of the car right before the car fired, not the first time I have heard this noise right before it decided to start. I was thinking fuel pump but, check engine tells me ignition failure? What in the world is wrong with this car now?

The car has has the main relay soldered about 100,000 miles ago as well as a new ignition switch about the same time if that helps.

Thanks again
Adam
