I have a. 89 gmc seirra 1500 4.3 six cylinder
it turns over a few times and starts but after
you drive it a little while it doesn't wana start
you can let it cool for 15-20 minutes and it
cranks back up I've checked the coil and
module there both good I just can't figure
out what's wrong with it

I'd check your coolant and cylinder head temperature sensors. Check for trouble codes, or test the sensors. http://troubleshootmyvehicle.com/gm/4.3L-5.0L-5.7L/how-to-test-the-coolant-temp-sensor-1
