Silly question but would that, or could that happen if there was a short circuit somewhere on the car for a brief moment, as with the starter motor?

But then the burning question is that if it cant pass current when its hot then why did the car just come back to life all of a sudden when it was nice and hot???

Not being funny or anything Jon, as a matter of fact i appreciate any comments towards this, but iv got to ask all the relevant questions along with the suggestions poeple will be making.
