So my 1990 deville overheats after about 20 minutes of drive-time. Issue 2: when I start car (when cold) it will start with no problems (sounds great) but when I drive for any length of time (5mins or more) even if it doesn't overheat and I shut down (to go into store) it will not start without sitting for several minutes first. It seems like for every minute of drive time it needs to sit that long before I can restart.
If I try starting before the time needed it will act like the battery is dead, but wait a few more minutes and it starts like nothing was ever wrong.
I've changed the heater core, water pump, starter, battery and fixed several ground issues. Any help would be great
