Could be a number of things but likely a dirty radiator or a thermostat that has been corroded and stuck. Possibly a water pump that is worn out. On some late models or foreign cars an electric fan malfunctioning.
My guess would be a thermostat stuck and needs replacing. Not a super expense but a couple hour job for somebody who knows mechanicing.
Good luck.
If your Yamaha TTR 250 starts but keeps cutting out after a fuel minutes, it might not be getting enough fuel. Check to ensure the fuel line is not clogged.
Depends on the engine but severe engine damage will start to occur almost immediately. It will run a few minutes until it starts to overheat then the engine will seize. It will not take long to destroy the engine.
replace your crank sensor....or when it dies dump cold water on it to see if it starts again
One common problems is a plugged catalytic converter, if the engine starts fine and then starts to stall or feel like it does not have any power after running for a while it could be the catalytic converter.. the engine starts loosing power because the exhaust has nowhere to go (the catalytic converter is partially or totally plugged) Compression starts to go down causing the engine to stall or die. If you leave the car alone for a while the pressure in the engine goes out slowly thru the catalytic converter leaving the car ready to start again for a few minutes but it will shut down again.
broken drive belt
it's your crank sensor as soon as the engine gets warm it shut offs. let it cool down and the car starts back up.
No, the thermostat controls the temperature of the engine coolant. As long as the coolant temperature is below the thermostat set-point, the thermostat remains closed. Once the temperature arrives at the set-point, the thermostat starts to open, sending heated coolant through the radiator. The radiator then cools the heated engine coolant and the water pump forces the coolant back through the engine. The heater control valve allows more or less of the engine coolant through the heater core. Since the coolant should be very near the set-point temperature of the thermostat, you should be getting hot water through the heater core to warm the inside of the vehicle. The engine coolant is there to keep the engine from melting down or from breaking metal parts and burnng off the oil. It just happens that the heated coolant is useful to warm the inside of the vehicle.
new molecules starts to form
when water gets heated it starts to get excited and it stats to boil and there are atoms inside which viabrate and makes the water boil.
I had a similar problem a couple years ago, where when on the highway it would begin to act as if there wasn't eneough gas getting to the engine to maintain a higher speed. It turned out for me to be a bad O2 Sensor located behind the engine going into the exhaust. I think it cost me about 40 dollars at autozone and only took about 20 minutes to replace. Since then no problems.
Check out your fuel filter it sounds as if it is clogged and after sitting for a few minutes the debris falls away and lets it start and run until it becomes clogged again.
you can check your engine codes of the module. Is it seized up? Is your engine getting hot? The module will show pending codes even if your "check engine" light isn't on. Another way to check is a little more simple... 1. take your radiator cap off. 2. do this when the car is cool to avoid injury. 3. turn your car on and let it idle for 10 minutes. see if the water in the radiator starts moving. If it doesn't and your engine temp. gauge starts to rise above normal operating temperature, then you have a faulty thermo stat.
