I suggest you call a qualified service repair man. There are as many ways to connect a heat pump as there are people doing them. Nothing is standard industry wide that has anything to do directly with color codes, so it would be meaningless to go into them here. The terminals may be adapted to standard but but the thermostat manufacturer may not follow any terminal designations.
However you may just have an extra wire touching one of the terminals inside the thermostat. You can check this by removing the cover. Look where the wires attach to the terminal screws on the thermostat. Sometimes a new service person cuts the insulation back too far here or in the outdoor or indoor units and a "whisker" from one wire can touch the other terminals. A whisker is not the normal case try and move it away from another terminal if its is touching there. However, you may have jumpers in place especially if you have W, W1, W2... at any of the 3 sections, meaning the outdoor, indoor and thermostat.
If you can tell me the terminal designations R,Y, W1, W2, E, G, O, (B)... at the thermostat and the color thereon each, then at the indoor unit terminals or wire designations and the color there, then at the outdoor unit and the color thereon each terminal or wire designation there. I might be able to help if the above whisker check you don't find anything.:

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.

most likely your compressor contact is stuck closed, and will need to be replaced. if the fan also runs when the compressor comes on you may have a short between the t-stat and unit. hope this helps.

are you speaking of the outside fan or inside? compressor should be a little warm but not boiling hot. the unit could be low on freon. if low it will run a while but the compressor will overheat and shut off leaving the fan running by itself ouside. if nothing outside is running check power. if you have power check the contacted outside to make sure it's pulled in. contacters are bad about going out on goodman untis. Also ants can get under contacts.
