Mystery starting problem

[TKO]

Here's the deal. Over the past weeks I have experienced a periodiac problem with starting and the engine just quiting. When it doesn't start it cranks just fine. I go thru my starting normal starting routine and it just cranks and cranks but doesn't fire. It also has quit a few times on me when driving. No sputter or cough,...just like someone turned the key off.
I have only experienced this a few times out of many starts over the last 2 months or so, but it is enough that I always need to cross my fingers before turning the key. It never left me stranded, but I needed to give it a 'time out' for awhile.
Yes I know... fuel and spark. I do know that it sparks when pulling a plug and cranking the motor.
I have done the normal seaches here and on Pelican, but would like to hear from someone with an early car with MFI. Points, dwell, fuel pump?

Any help would be much appreciated. I need my confidence back so I can start driving the car all over the place.

69Sman: Yes there is a possiblity of a previously installed kill switch. I found a switch under the radio area, not mounted to anything. I think a tried starting in both positions one time that it didn't fire. Good lead though, I'll try it again!

Sithot: The car was not completely apart. The glass was out, doors off, hood/deck/sunroof off, all seals and trim removed, but the most of the interior and motor stayed intact. As far a WOT starting, I have also experienced this when it is stone cold.
My hunch is electrical as well. I have put on new wires and plugs. Should I check points and rotor next? I'll research the fuel transducer.

Shawn: No need for the sad face about carbs, you can run a sport muffler!

Thanks for the tips guys...
