So I'm cruising along at 50mph and suddenly the engine cuts out. No sputtering. Just dies (and yes it has gas). So I coast over to the shoulder and recycle the key. All electronics work but it won't start. Doesn't crank. Just silence. Try it a couple more times. No joy. After about 5 minutes of figuring out who I'm going to call to come get me I try it again and it starts right up. I'm only a few miles from home so I take it back with no further problems.

I get home and pull codes. The only code is the P0410. I used to have this all the time but since I replaced the secondary air pump a few months back it's been fine.

The final clue is that I can't erase the codes (I used to be able to with this reader). It lets me go through the steps and says they are erased. But when it is done the same code is still there.

So I've been reading up on the Mystery No Start issue and plan on touching up the solder joints (or sending it to Tighed1). But I'm curious about not being able to erase the codes. Is that a common symptom or is there something else going on here?

Thanks
