My 1982 gmc truck won't start sometimes and will stalled sometimes.When it decide to stall on the road or just iddling its just as f the motor died no missing or no noise of anykind its just dead.When it doesn't start I only fires once when I release the key and it sounds like a little back fire doesn't mater what I do it doesn't start again until its ready sometimes 2 minutes sometimes 30 minutes and it went up to 50 hours until it got ready to start again.
Anyone have any ideas of what the problem is?

Rut-ro, GMC ruck? Seriously, pay close attention to ignition modules or components. It really sounds heat related.
You can have parts tested free at auto zone.
