SOURCE: responce for clarification

You'll only see good circulation when it's at operating temperature & hot enough for thermostat to open, allowing coolant to flow through the system. Hope you had heater on (not defrost) while you were letting it run/circulate. I usually wait for rad fan to come on 2 or 3 times, before I put cap back on. Rad fan comes on to cool what just came out of engine when thermostat opened, so when you see good flow, you'll probably see fan come on shortly after.

When it stalls out did you check the spark? I suspect the engine is losing spark due to an ignition system failure.

run fault codes and look for EVAP solenoid /sensor / valve as you may be developing a vacuum lock in the fuel line that is starving the fuel system.
