You have a leak somewhere. Good chance it is a leaking check valve, located either at the pump, and at the end of the pipe down the well.
have the coolant system pressure tested to help diagnose your problem.
2 reasons for the system to cut out, low pressure, and high pressure. I am thinking you are experiencing low pressure and need to recharge your system.
A Low Pressure System
what causes air injection system pressure to be stucked in cars
Hi, this is a common problem with subaru's - you need to get the cooling system pressure bled - i.e there is air in your cooling system.
Low pressure
High pressure tells me of a possible head gasket problem. Have the cooling system pressure tested by a reputable garage; this will answer some questions.
Low and high pressure systems. Obviously if you have a Low pressure system the barometric pressure will get low. High pressure causes the barometric pressure to rise.
The problem is a leak inside the high pressure oil system. When it is hot the leak expands and causes the truck to not start.
dirty coil
Expansion of the water inside due to heat causes the system to be pressurised.
A tornado has low pressure in it, but it is not considered a low pressure system as it is too small to be its own weather system. The low pressure in a tornado causes the surrounding air to rush into it.
