WIERD STARTING PROBLEM
 

So this problem seems bizarre to me, but occassionally, I go out to start
my car and it tries to turn over however it won't start. I can try it
several times and nothing. However, typically if I wait about 20-30
minutes and go back and try again, it works just fine.

In addition, after I have this problem, if I only drive a short distance,
turn it off, and then try to start again, I have to give it another 20
minutes. But if I drive a longer distance the problem doesn't resurface.

I seem to have better luck with I put premium gas in it. But whenever it
does start, it drives just fine.

Other than that, its completely random and unpredictable. What could this
be??
