You just may have a hairline crack on one of your computer modules, and when it heats up, it expands and the connection is rejoined. That is one possibility. If you can when the temp is below 70 and it is causing problems, have someone put a code reader on it and see if all systems are working. Once the engine warms up, the under hood temp shuld be above 70. Does that help?
