fans not working big cruise n Sunday

[Steelrat]

Background:
Taurus fan set up wired with high - low switch
BOSCH 75 amp - 0 0032 002 15 relay
Fans have worked flawlessly for months.

Fans stop working while on the road. On side of road had to bypass relay and switch- positive from battery to low speed negative to ground. Got me home fans ran fine all the way

Rewired front to back switches to relay to fans.

Fans only run for 20 seconds and shut off
Battery fully charged - Reading 14 v on gauge.
Have spare relay and Taurus fan, swapped out both.
Same issue, fans run for max 20 seconds shut down.
Wait 1 munute, will run for 20 seconds again.
If I direct wire fan to positive and ground to neagtive also runs for only 20 seconds...battery not enough power to sustain fans?
Advice??
Thanks

I can't see both fans are bad and you said they work properly for 20 seconds. How are the fans kicked on. Could it be that your temp switch is bad. Check and make sure that its grounding at the proper temp and staying that way. I'm not familiar with the taurus wiring setup so if you fill me in I can help some more.

It sounds like you have a self-resetting circuit breaker in your power source that is shutting down the fans.
