Pentair short cycling when I turn on bubblers & wall fountain

Having an issue with my Pentair system and hoping someone can point me in the right direction.
Whenever I open the app and turn on the bubblers and wall fountain, they start right away. They run for a couple minutes, then shut off by themselves. This also applies to my pool lights as well.
About 30 seconds to a minute later they come back on, run another couple minutes, shut off again … and it just keeps repeating that cycle.
I only have one schedule set (6:30p–8:30p every day), but the bubblers and wall fountain never actually come on at that time.
Any ideas what could be causing the short cycling or why the schedule isn’t kicking those features on?

You have a separate pump for these things?

Yes.
I haven't had an issue before. This appears to be a "new" issue.

Motor capacitors could be going out. Easy and cheap fix. What model motor you have?
If you have a multimeter that can test capacitance, you can check before you buy one.

I’m not sure about the fountain and lights but my bubbler was tripping because the outlet keys were too small. Sizes them up one size and never happened again.

Just had this exact issue, after troubleshooting everything, a pentair rep came to my house and replaced the control board. Fixed the problem

How much did that cost? Would you happen to have the name of your Pentair representative?
