[DeTomaso] 1972 pantera slow starting

[LEVITT1946 at aol.com]

Hello Friends ,
For those of you that last followed my clutch saga /I ended up replacing  
bent linkage and the master cylinder .
 
Now here is the new problem. From a cold start the car starts fine.  When I 
drive a few miles and the car is fully warmed up I pull over and shut  down 
the engine. I try to restart the engine and its like this . chug chug chug  
almost like the battery is dead and the car starts. 
 
Is it the timing ? 
 
The starter is fairly new so i do not think its the starter . Is it  
possible to connect the wires incorrectly on the starter to cause the  starter to 
turn slower when hot? 
 
I also noticed that when i start the car at night the headlights will  not 
come up for a few minutes . Wierd?
 
Maybe this is all related . The alternator was recently upgraded to  100amp.
 
All help is greatly appreciated
