no cranking after shutdown

[lanny]

Hi guys good day.Got me a scare today,as i was motoring along in stop and go traffic no a/c on went shopping and on my return approx 20mins went in the car and attempted to start.ignition lts. on but no crank i tried cranking for some time but to no avail.some-how before switching off i noticed the temp was about 100deg.but that didn"t phase me.after a few attempts to start i waited fow a while for the engine to cool thinking somehow that was related to my problem.finally it started and off i went until i reached home.i shut the motor down and cranked it and it prompted started.guys did anyone of you out there experience this phenomena and how did you prevent it from happening again?please chime in as i don"t need this to happen again.thanks a million.
