Are a lack of power during the day

it gets to the point to where I lose MPH when going up all hills and it takes a 1/4 mile to
get it up to 45 and longer to get it up to 70

it was quick just a month ago also as it reaches normal running temperature that’s when the power starts to lose it bad yet it runs better at
night until it gets warmed up again

Gentlemen, have a 1997 Pontiac Grand Prix, 3800V6 engine which begins to overheat while stopped.  Suspect both cooling fans are inoperative.  Have checked main 30 amp fuses which are good.  Can you assist with diagnostics on how to determine if relays and/or cooling fan motors are working or not.
