Andy,
  Finding TDC-there is a pointer on the timing chain cover that points to
a notch in the front crankshaft pulley at TDC.  But, there are two TDCs,
one for #1 and #4 and they are at the same position.  Since you got the
engine running at all, though, you have it right enough.
  If you have established that #1 wire is at lower front, say 5 o'clock
on the distributor, you have it right.  Then, since the rotor turns
anti-clockwise, the 1 o'clock is #3, the 11 o'clock is #4, and 8 o'clock
is #2.
  If you are out of order, it may run at idle but won't rev up. There
would not be enough power to drive it across the driveway at less than
about 4000 rpm, and you can't get there.
  How to tell TDC on the compression stroke--remove valve cover, turn
engine to get the markers aligned. Look at #1 valve rockers. Both should
be free, moveable, with a little clearance, as this is when the valves
are closed and engine would be firing. That's the sure test.  Others
include having your thumb on the sparkplug hole as you crank the engine
and comparing the push of the air on the exhaust stroke to that of the
compression stroke.
  The sudden stop is likely to be an electrical problem. As others have
noted, fuel supply problems usually cause the engien to stumble to a
stop.
