The small power supplies provided with the sets are marginal at best. Running a locomotive that has not been lubricated, along with cars that perhaps have a little extra drag (again from lack of lubrication, or from collecting crud off the floor or carpet) can cause the circuit breaker in the power supply to drop out. It usually will automatically reset soon after the overload is removed. This is as you have described.
Once the circuit breaker trips once, the next slightly high current event will cause the breaker to trip at an even lower current level. Just a vicious cycle that results in lots of frustration.
If you have a volt meter, check the track voltage when the train stops and before you do anything else. If it is zero, then the problem is most likely the power supply circuit breaker.
Cleaning and lubricating the locomotive, cleaning the track (which might eliminate the slowing down in spots), and putting a very small amount of lubricant on the truck bearings should help, but the starter set power supply is still marginal.
The real permanent solution is to get a new, larger capacity power pack, as well as doing the above maintenance.
Hope this helps,
