Unhappy 97 Blazer runs great in cool weather, but Dies in Hot Weather!!

Hubby's been trying to figure this one out for a friend.

He has a 97 Blazer that starts fine, runs great with no stalling when the weather is cool. But when the weather is hot, it will start and run for a block or so, then Die and not start again for a couple of hours. Then Die again as long as the weather is hot.

When he tries to start it, it sounds like a fuel problem. The fuel pump and filter have been replaced.

Now, the engine itself is not getting hot...just reacting to the weather.

Any ideas????

Yip, ignition switch, it is a black electronic module in the steering cokum.

Info on replacement is in the FAQ at the top of the blazer section.
