Question about liftmaster Chamberlain Garage Door Opener Transmitter 300MC
Move the safety sensors out of the sun, You can try to put up a piece of cardboard or something to sheild the eyes from the sun ( do not block the lenz of the eyes)

I'm a license electrician, I can only think of two possiblities, either the sun is interfering with an infrared safety switch or it's causing your safety switch mechanism to overheat.
The most common is the floor level beam, if possible try to shade your safety switch plus a few inches beyond the lense.
If you have the touch strip on the bottom of the door I'm afraid I don't have a solution beyond replacing the strip and I'm not sure that will work.
