That sounds like the motor is getting too hot. There is a safety feature in the pumps that will shut it off when the motor begins to over heat. When it shuts off, does the motor feel hotter than normal runnng? DO NOT touch the motor because if it is hot it may burn your hand.

Things to look for that may cause this issue:

Air in the pump basket area. If there is a small air leak, the motor would be working at the same rate, but not moving the same amount of water.

Too high, or low, of pressure on the filter gauge. If it is too high and you have not cleaned the filter yet, try that first. If you have cleaned the filter and the pressure did not go down, you may have a blockage somewhere in the system. If the pressure is lower than normal, you are not getting the flow of water through the system as before. This could be a blockage from the main drain/skimmers to the Inlet on the filter. Or, an air leak.

Dolphin pool cleaner stops working after a 15 to 30 minutes. Even though the cycle time is set to 8 hours. How can I fix ?

It sounds like you might have a problem with the impeller or drive shaft, which are both common problems with these pool cleaners. Clean around your impeller and your wheels, axles, etc. If these do not cure your problem, it is probably an issue with your electrical system.

Pool pump shuts off after a couple of minutes and seems to be hot

You problem could be one of several things. First, pumps have a thermal protection switch that shuts the pump down when overheated. You could have rust after only one season that overheats the pump and it shuts down. The switch could be bad. There could be an electrical issue when running it on a long cord of the wrong gauge. Plug the pump into an outlet without extension cord and see if it makes a difference.
