the tumbler is broken..the slit it goes into. the key ignition is messed up.
Because it's in park.
Depends. An older Diesel is likely to keep running. A modern, with a full set of electronic engine diagnostic might not.

A coolant leak while the engine is running is likely in the water return hoses. The vehicle can be standing still and in park, but with the engine running the fluids are still being pushed through the system to keep the engine cool. The water return lines generally run from the top left of the radiator when you are standing at the front of the car looking at the engine. Any leak in that system will likely not continue once the engine is stopped as the fluid no longer is pushed through the system.
If the engine is running and the alternator is good. If the engine is not running, no.
Check to see if engine is getting fuel and spark
It can be a leaking injector that floods the engine when it isn't running. GoodluckJoe They asked about a problem that occurs AFTER it's been running a while...not after it's been sitting, with a pressurized Fuel line.
No , just when the engine is running
Get engine running. While the engine is running disconect the POSITIVE termninal from the battery. If the engine dies, the Alterntor is bad.
The alternator - it provides a charge to the battery while the engine is running.
Is the engine running ? no
engine is running lean while eccelerating
