It sound like the limit switch is shutting off and not coming back in to play .

check air switches, or air button tubing disconnected. also if calling for heat and htr does not work pump will run continuously unless you turn t/stat down

I don't understand everything being asked, so add a comment any time.

Problem1 is excessive electric bill.
Suspect is new 120Volt Taco recirculation pump.
Look at motor nameplate for amps and watts and HP. Taco pump is usually robust 1/3 HP which is 252 watts or same as running four 60 watt light bulbs.
If pump runs 18 hours per day x 252 watts = 4536 watts or 4.5 Kilowatts per day
Buy a kill-o-watt meter that plugs into outlet, and plug Taco pump into the meter for 48 hours.
This will give you total watts used for that time period.
1000 watts = 1 kilowatt.
Electric bill is probably 12 to 20 cents per kilowatt.
So if Taco uses 4.5 kilowatts per day, that is $.54 to $.90 per day multiplied by 30 days.
So cost is $15 to $30 per month.

Problem2 is Taco runs too long.
Taco operates either by thermostat or by timer. You choose which mode by using slide switch that is usually located under the timer dial. Set switch to TIMER to use timer, and ON to use thermostat, and off to turn TACO off.
If Taco is set for thermostatic operation, the Taco might be defective. Or there could be crossover problem at single handled faucet.
Another problem could be air in the water line: install air vent.

It's not possible to stop the spa from starting up after a power loss. Most spas go through a self test then try to reach the last set temperature. Pump 1 usually runs the filter/heater, once it's activated it should run for 20min or until you turn it off. The high speed on pump 1 should always work. One problem with the pump may be that it's heating up and the internal high limit won't let it turn on. When you shut the pump off, the motor gets even hotter for a period of time since the fan is not turning, it may be getting hot enough to trip the internal high limit so that it won't turn on until the motor cools down. It won't turn on even if the topside control indicated that it should be on.

check strainer and skimmer for excess debris that will cause low flow to heater thus not engaging pressure switch.make sure filter is clean.if all of these check out ,take continuity reading on pressure switch.if no continuity,try to adjust pressure switch if it wont adjust ,its faulty.take extreme caution when adjusting make htr will shut down when pump goes off

Headlights are wired to receive a constant "hot" even when your keys are out of the ignition. Your problem, more than likely, is in the switch. Depending on what type of switch you have, you can expect to pay between $20-$80 for a new one.

Remove all speakers from the receiver and try powering it up again. If it still shuts down odds are it needs repair of one of the output channels.

check for proper pump pressure. Restricted fuel flow. Proper venting of fuel cap.
