The fan motor is getting hot and going off on the internal overload in the motor.
This is caused by either a low voltage, a bad capacitor, or tight or dry bearings in the motor.
To check the bearings turn the power off to the unit, then spin the fan blade if it spins freely then the bearings are ok.
To check the capacitor you will need some kind of
tester or you can buy a capacitor and replace it, that's what a lot of people do. They usually don't cost very much.
To check the voltage you will need a voltmeter and measure the volts at the unit.

how to fix

SOURCE: dryer runs then stops after short periods (5-10 mins)

THere maybe a thermal limit sensor gone bad. Keeps the dryer from over-heating. Located behind rear panel on most and mounted on the heat tube. Verify with volt/ohm meter if possible

SOURCE: The heater makes a banging sound after the burners

What you have is a water flow problem. The water should be going through the heater but it is by-passing it. The water inside the heater is boiling and trying to expand as steam that makes the banging sound. Their is a internal by pass in the water manifold on the side of the heater. If you take this apart you will find a disc on a spring contraption, if it is stuck open the water goes past the heater but still has pressure to kick the pressure switch and fire the heater. Either clean or replace this assembly. The other thing to check for is an external by-pass. This will be a gate valve bridging the inlet and outlet pipes. If you have one of these it should be 80-90% closed or the water goes through it and creates the same problem. This is not on all systems so don't be alarmed if you don't find it. Good luck.
