The only thing I can suggest seeing you have done so many replacement of parts is to have the vehicle hooked up to a "live data" scanner so a tech can watch the system during the conditions you have stated. I am going to assume that you have already cleaned or repaired the sensors and computer ground supplies and watched for stable voltage from the power relays.

Not computer ground supplies it runs great as long as it is not warm and humid it's just frustrating

A weak ground can cause a circuit to run too warm, and put humidity in the mix and the problem is expanded, so they need to be clean, no corrosion even a small black spot can cause trouble, so if all the powers and grounds are clean then move onto the "live data" test, cause if you do the test and it finds bad grounds then you spent money needlessly.

Thx
