My Jandy Variable-Speed Epump runs for a random length of time (hours/days), then goes offline. I must hit the reset button to restart the pump. The Pump is 4.5 years old. Does not appear to be overheating. All new filters, all baskets are clean, and no obstructions going into the pump. 15 lbs of pressure is my current reading.
 
Welcome to TFP.

What controller is the Epump connected to?

What specific model number pump are we discussing?

Completely programmable and customizable with the Jandy® AquaLink® line of automation systems, iQPUMP01,
or the JEP-R controller.

What control panel do you have with your Aqualink RS?

Can you turn on your pool light or other devices when the pump is stalled?

I wonder if your Aqualink is the problem and not your pump?

Not sure what you mean by "control panel". I sent an image of where the reset button was that shows the entire panel.

The pool lights are a problem. I have two lights. Both come on for a few seconds, then one goes off completely while the second starts blinking like a strobe light.

Pump seems fine, but keeps being turned off for some reason.

Your outdoor control panel has no display.

Do you have indoor control panels or app on your phone?

You cannot control much on the outdoor Aqualink panel and you need a full control panel someplace.

Possibly a problem with the driver chips.

Unplug the lights from the Aux Relays.

4.1.1 Driver Chips
The driver chips can be thought of as a series of small relays.

When one of the driver chips receives a signal, it closes a contact which passes 24 to 32 VDC to the appropriate relay coil socket, in this case AUX 1.

Each relay driver chip activates a specific set of relay coil sockets (see the chart below). If a driver chip fails, it is usually caused by either shorted relay coil wires, a shorted relay coil, or a relay not designed for the 24 VDC coil voltage (i.e., 24 VAC rather
than 24 VDC).

The relay coil provides resistance (approximately 300 Ohms); if there is no resistance, the driver chip circuit will be damaged.

The driver chips (U6) drive the relays.

They are in a socket, to simplify replacement in case of damage.

5.4 3 HP Relay.

5.4.1 Operation

1. A standard 3 HP Relay's coil is supplied with 24 VDC from the power center PCB via one (1) of the driver chips.

When 24 VDC is received by the relay's coil wires, it closes the contacts that complete the circuit to turn on the equipment (i.e., power supplied to Line 1 goes out Load 1 to the equipment).
2. Standard 3 HP Relays may be wired to activate a 120 VAC circuit (i.e. Line 1/Load 1) or a 240 VAC circuit (i.e. Line 1/Load 1 and Line 2/Load 2).

Note If a relay's coil wires are shortened, or an AC relay coil is plugged into a relay socket, when that circuit is activated, it will
damage one of the relay driver chips on the power center PCB.

Specifications.

Maximum Contact Ratings:

3 HP at 240 VAC

1 1/2 HP at 120 VAC

1500 watts (per contact) - Incandescent

Relay coil - 24 VDC

Resistance across coil - 300 Ohms

Amperage draw of coil - 0.10 Amps
