Read the required installation and maintenance protocol to see if air filter has been cleaned regularly, or the condenser coil might be dirty.
Required maintenance can be done by service tech recommended by AO Smith.
Contact AO Smith to find trained person, and next time, do not install expensive water heater since all savings disappear with service issues.

13Mb product manual is a big download ... electrical info page 13:

Recommended both water heaters require dedicated single-phase 15 amp 120Volt line with correct polarity. This is 14 gauge wire and 15 amp breaker for each unit.
I would put both water heaters on surge protection and GFCI. Most water heaters are not protected from surge, and manual says line noise can affect operation of water heater.
Your local code would say if GFCI is required. Install GFCI breaker in main panel if required.
Install inline surge protector: Or add main breaker box protection.

If the igniter is not turning off, then that would explain early failure, and it would be caused by the control chipset

Unit is probably rusted out:

Reliance is AO Smith. I recommend the AO Smith line-up of water heater brands as best because air intake screen is located on bottom of unit and can be cleaned by homeowner without removing combustion parts, and because AO Smith posts service manuals.

Thank you for providing clear description of product:
Your water heater has intellivent gas control thermostat.
There are always problems with water heaters. It is a huge field.

1) Open following link for AO Smith service manuals.
I do not see service manual specifically for the GP series.

2) Open following link to identify gas valve and download typical service manual:
Some AO smith power vent models have intellivent gas valve, and some have smart valve gas vent. Older models might have knob-type gas valve.

FPSH series is a power vented residential gas water heater.

1) The blower is plugged into 120Volt outlet. If blower has short, then it will trip breaker.
Blower could be Fasco model 7021-10195, or 7021-10770. Call AO Smith: 1-800-527-1953. They will need model number and serial number located on label on side of tank.

2) Before calling AO Smith, check outlet with circuit analyzer. Outlet must have correct polarity and must be grounded. Unplug cord to water heater and run continuity test from ground prong on electrical plug to manifold tube on gas valve.

3) Also if a fluorescent light fixture is on the same breaker, that can cause burner to short cycle.

4) Connect water heater to different outlet and see if problem continues.

5) AO SmIth has service manuals for the FPSH series that download to your computer:

Check all wiring at water heater and possible upper thermostat is bad, and in need of replacement.
