main fuel relay

Apparently these things can go bad when the weather gets cooler as well. Since it got cooler here in texas, my car has been giving me problems with dying while im driving it every once in a while, along with the comming symptoms assiciated with a dying main fuel relay. It seems funny to me because I have read 9187234 posts about people having trouble with their fuel relay when the weather’s hot, but i guess they can go bad when it’s cool/cold as well. I still dont get it why it made it thru a frying pan hot texas summer, and picked the fall to start having problems.
