sounds like you have a coolant leak inside the engine compartment and its steaming off the engine heat. You need to check heat sensors also as those fans need to run to keep motor cool. Beware , those fans can turn on at any time so keep hands and fingers clear of them when checking or workng near them.

SOURCE: overheated due to a heater
I hate to have to tell you this....
Because of the overheating you have a blown gasket. Either the intake gasket, or one if not both head gaskets. Pull the plugs and see how many are wet or smell like anti-freeze.
Depending on the type of heads, aluminum or cast iron, they may be warped as well.
Before you grab your crying towel....it is also possible that anti-freeze from the leaking hose found a way to seep into the exhaust pipes and it will take awhile to clear out.
Hope this helps.

Overheating can stall the fuel supply reduce the fuel flow and also can be related to failure of ignition, if igntion system fails.
The overheating of the car can be due to many reasons and you need to check on each one to confirm the working of the system.
1. In the first place the working of the engine must be assessed. it must be smooth with a good indication that the tuning timing and the power seems good. This will confirm that the settings of the engine is good and so there is less scope that the engine seems to heat up on its own.
2. Secondly the radiator pressure cap must be tight and good, the radiator MUST not loose coolant after a run or in a few days time- since this must be a sealed system and there is no scope of water overflow or loss unless there is a leak- sometimes the leak is too microscopic as under high pressure only steam might escape and so reduce the coolant. So check for leaks while the engine is hot , specially the radiator, the hose or the fittings.
3. The working of the water pump must be good to ensure a good flow and circulation, so check for leak in the water pump, check for presence of water in the exhaust or leaking on the engine gaskets.
4.Make sure that the coolant is good and clean if not drain and refill , if there is presence of rust please have a good flushing of the radiator or else the chances are that the radiator ports can be blocked and reduce the efficiency of the cooling .
5. Finally the cooling fan, the radiator fan must be working, check the thermostat/thermistor to work accordingly with good flow, have a good water jet wash on the radiator for a clean radiator cooling fin exposure
