Wont start on a hot sunnyday

It is likely a fuel pump problem, confirm this by spraying starting fluid into the engine when the no start occurs, if it fires up then you have a poss fuel pump sticking problem.. This assumes you mean the engine is being cranked over with the starter but does not fire up.
