One for the electrical gurus........auto switch off

[thailoz]

I have an Idea but not sure how to go about it

I want to have some of my switches auto reset when ign is off.. for example :-

Fuel pump circuit

What I would like is when the ign is on I could push a momentary on button which will then switch power to my fuel pump also lighting an ind lamp telling me I have power.
Then when switch the ign off the switch resets ,so that every time you get in the car you have to push the button to start the car (sort of security device if you like).

So can any one shed any light on how to do this please.
