1972 dart - stopped running while at 50 mph ? no warning

"ok , so i tried to check the timing , with a remote starter switch , but could not get the timing light to flash much at all , one or two random flashes , and nothing . tried two different timing lights a few times each , same result or nothing . i feel like i am doing something wrong . so i could not find a solid core wire , so i used what i have . i tried to check spark at first with the remote starter . zero from coil or plug wire number 1 . then i re read what you said a few times ( i takes me awhile ) and tried with the key . from what i could see looked like an ok to good spark , had the gap at about 3/8" , from looking between the bottom of the hood and cowl and with sun in the mix . heard a zap zap sparky sounds too . tried the same thing by putting the wire with tester in the cap where number 1 goes . got nothing , no spark , no happy sounds . then pulled the cap , pressed the remote starter , rotor is spinning , points are opening and closing , but no sparky goodness from those either ."

If I am reading this correctly ^^^^, does this not mean that the ignition system is in fact working with high voltage coming from the coil tower? Sounds like it is not getting to where it needs to be.......

I would be looking at the components from the coil tower to the plugs, and of course the timing chain or loose distributor.

BTW.......With that shorting as @Bewy suggested, I'd be back checking to make sure nothing else got fried (check for coil tower output again).

Good Luck
