Motor starts stays running for maybe 3 to 5 minutes then shuts off then i can restart again in 5 minutes?

I would start by getting a can of carburetor cleaner and have it 'at the ready' and try the 'start, run stall, start run stall' operation again. Only THIS time, once the engine begins to stall, give it a couple of quick shots of the cleaner into the air filter to see if it stays running on the cleaner.

If it does, then it's still a fuel problem. If it doesn't, then it probably an ignition problem. I would be sort of leaning towards the ignition coil getting weak. The reason I'm saying that is your statement about it running (I'm assuming cold start) for at first, 10 minutes then it stalls. Start it again and it runs for a couple of minutes and stalls again.

This could possibly be from the coil getting warm/hot and not producing the needed spark. After a 10 minute run it simply gets too hot and stalls the engine. After the next restart, the coil is already warm from the engine and so it don't take as long for the coil to get hot and stall the engine again.

Hope this makes sense and helps you out.

Most likely your problem can be with the motor control board, with the kids, the motor is not pull many amps, so the treadmill will operate normally. Replace the Motor control board

may be a thermal Issue, u can check the fan running

One bulb or 3 bulbs. If 3, swap two. if one try to troubleshoot the board. Look for burns or distorted caps.

This is a sign of a bad motor. There is an overload protector on the motor that when the motor overheats it shuts the motor down.

You could tripping the high temp limit this will be located near the heat exchanger When it shuts how long does the blower motor stay running? Do you have a meter?

Maybe the timer or wires not hooked up right or motor if u hear like a buzzing sound when u push start it's the motor

sounds like your motor is overheating or going bad. sometimes lint built up around the motor can cause it to overheat. or the motor is dying.

when you try to start it again do you hear a humming comeing from the motor? can you jump start it by turning the drum while holding the start button? If you say yes to these questions you have a bad motor.

replace motor drive,,,defective motor...onthejob
