need help to find pump or similar

Pumps usually have some type of internal thermal shut off and/or over current protection. It sounds like your pump is cutting off for that reason. Ive found that older pumps can sometimes experience water creep between the cord and the potting resin on the motor block....or through some other leak path. Looks like this shark pump is actually a sicce syncra motor block. I wonder if you can find the same size standard syncra pump and retrofit it with the skimmer impeller. Or better yet find a suitable dc pump replacement
Ah IIRC the old askoll pumps are also rebranded "Laguna" used in pond pumps. Might be able to pull one out and retrofit it...but for something that big id go DC.
DC pumps are the way to go. I have 4 dc pumps in my sump and i can barely hear a thing. Gone are the days of 60hz hummm resonating through my sump and stand.
Just ask gveng:

I was gifted an Aquamaxx Cone - S skimmer and the pump didn't work without taking the intake apart each time it shut off, so I bought a slightly bigger DC version pump (Jebao DCA4000 needle wheel version) and made my own venturi nozzle and it's a beast. After the initial break-in, the pump is dead silent and pulling just as much, if not more than the previous AC pump, plus I can fine tune it unlike the AC version.
Here’s the skimmer in action with an elongated tube to fit my old sump while I work on my tank. I bought some 3/8” plastic rigid tubing for my skimmer cups to make drains, so I used a small piece for the air intake to make the Venturi. I used the white PVC fitting to test the position of the air intake to maximize air, once I found the right spot, I then used a black fitting to match the pump. I had an old uniseal that fits snugly inside the PVC fitting to reduce the water intake, which really helps create finer bubbles and may be necessary to use, as most Venturi’s have a slightly smaller intake.
The Venturi that came with the pump didn’t even fit the intake at all, which is weird. I’m sure I could’ve cut it down and made something to fit that, but the PVC fitting worked perfectly for my application.
