Default throttle control fuse blown

I was driving in 101 F weather the coolant temp was 220 F and car was running fine (2001 z06). I stopped for an errand and when I restarted the car it ran rough, dashboard said reduced engine power / traction control/ check engine. The gas pedal didn't work and engine idled about 1500 but rough. I limped back home and let the car cool but in the morning the same thing was happening. I checked the forum and cleaned the ground connections also unplugged the battery cleaned contacts. Still didn't fix it.
I checked the fuses and found the throttle control 15 A fuse blown. Replaced it and car runs fine. Has any one had this happen or know if this is a recurrent problem in hot weather.

Default codes on computer

the codes on the diagnostic are 28tcs - C1225, C1278 and 40bcm - B2597, B2721. Not sure what that means.Any help is appreciated.

C1225 RF Excessive Wheel Speed Variation
C1278 TCS Temporarily Inhibited By PCM
B2597 Traction Control System Switch Circuit
B2721 PASS-Key Detection Circuit

None of those look like codes that should blow a fuse

The first 3 are traction control related and shouldn't affect the throttle control as far as I can see

I'd replace the fuse, reset the codes and see how you do. Could be a one off.
