Central air question please help.....


Hi everyone I'm new here, i have a question about central air, my unit's been running fine for ten years but this year the fuse in the main fuse box frequently jump off, if i set the temperature to 25 is O.K., if 24, the cool air will run for 20 minutes and the fuse jumps off, when that happen, the main unit is still running with air but no cool air, the condenser unit with the fan outside the house will stop. I have to turn off the control unit, reset the fuse and wait for few minutes before i can restart again. This really bugging me, does anyone knows what i can do? Should i get a higher amp fuse?

P.S. i replace the 1/3 hp dead fan motor at condenser unit to 1/2 hp two yesrs ago because 1/3 hp motor was out of stock, it was running fine for the last two years.
