Okay one day I'm driving down the street pulling up to the stop sign and I push the clutch in as I'm coasting and it just killed all power and then it died instantly when I turn the key to the on position is no power there's no bells and whistles are no dings there's nothing you just no power I'm thinking clutch safety switch was bad but also related to the pigtail issue on the distributor to a bad plug from blue oval Industries

Without knowing the year, engine and modifications, this will be a guess.
So until you can type more info, go ahead and check those, the ignition switch (there was big a recall) and fuses. Killing it with a clutch pedal push also makes me wonder if some wires got in the way and grounded.

Recall on Ford Ignition switches:

Revised 7-June-2014 to add Torx bit picture and source. Also added replacement ignition switch wiring pigtail picture, part numbers and sources.

Some of the symptoms of ignition switch problems are things that don’t work or are intermittent like radio, turn signals, wipers or heater.

There was a FREE recall on Ford ignition switches. They overheat and sometimes catch fire. That burns up the steering column and sometimes the car interior. Since this is very old information, you may not be able to get the switch replaced for free anymore. The auto parts stores sell the switches for $13-$15.







While you are working on the switch, check the wiring and connector closely. A replacement connector with new wiring pigtails is available from most auto parts stores

AutoZone and Advanced Auto Parts have the same Part Number: 434 - may have to order, not always in stock

Advanced Auto Parts alternate part number: PT5534



Saleen0679 was nice enough to dig this up for us awhile back: How to replace ignition switch on 1979-1993 Mustangs.
