I have a Chevy s10 that will die in hot weather. Once I stop and turn off the ignition it will start again and run great until it happens again usually 30 minutes or it may not happen again at all the rest of the day. Hottest day of the year here yesterday. I could only run it about 10 minutes before it died. (Died 5 times) This morning ran fine on way to work (30 minute drive). Any Ideas?

You obviously have a heat related intermittent problem that you have to be prepared to diagnose whens it happens as anything else is plain guess work. If all the symptoms are as described what you have to be prepared to do is to check for spark outputs and fuel pressure available at the fuel pressure test port when the truck quits. To check spark outputs you will have to unplug spark plug wires one at a time and crank the motor to see if the spark outputs at the plug end is strong and consistent. Be sure to have what you are using connected to a good ground or hold the screwdriver blade close to a good ground to see if the spark is good. If you have strong spark and the motor will not start, move on. To check for a primary ignition problem, you will need a 12V test light connnected to ground and probe the white wire at the coil while still connected to the coil. Turn the motor to on and the test light should light. Crank the motor and the test light should blink very quickly. If it blinks and no spark, chances are the coil is no good. If it doesn't blink you will have to check the inputs to the module as in wiring, crank and cam sensors. To check for fuel pressure, unscrew the cap on the end of the fuel pipe usually located behind the rear on the intake plenum. Try cranking and poke the plunger inside the valve and fuel should shoot up with pressure. To be accurate you would have to screw on a fuel pressure tester. If the pressure in down, chances are the pump or the sender has had it, but you should check the wiring to the tank. Good luck.

vapor lock. Try running a name brand of gas and see what happens.
