Well, I  have had to replace my TR4's coil several times since 1968. 1st  in
Indianpolis going to NYC from Norman OKlahoma in 1970; 2nd in Baltimore  in 
the
1980's. Typical symptom of bad coil- OK when cold- opens when HOT  (99^ day
too). Then in 1999 I put a Mallory Dual Point and Lucas Sport Coil  (from
MOSS)-- No problems since except blown condensor  (2005).

It has been my experience that coils frequently (ALL of mine) fail  by 
providing a weaker and weaker spark. I once read this and it is the test  I use:
 spark color 
blue-white    tops
yellow-white  great
yellow -orange  not very hot
orange-red weakest
 
I have checked coils this way for years and have replaced several coils in  
my cars when they were low on the list and have seen dramatic change in  
performance.
