Under the hood & there's one next to the steering column under the dash.

What is your question?

2008 Ford Explorer Limited V8.....After driving 20 miles of less, turn the engine off, come back a few minutes later, try to start the explorer and it won't try to start. It doesn't try to start at all. The accessories will play(windows work, radio works, etc.) but the engine or starter doesn't make any noise at all. After sitting for 20-45 minutes, it will start. This happens occassionally...perhaps every few months or longer. Sometimes more often. I can't pinpoint what the situation is or when it decides not to start. We've replaced the battery twice, starter, put a heat shield around the starter, had electrical system checked, put a second selonoid on. Nothing seems to correct the problem. Please give us the answer....thanks.

What makes this problem better or worse?

When the engine is hot
