[Magic21]

Car will run good then cut off after 15 or 20 min, will not restart for 15 to 30 min, ign modual checked good so did coils. is like you turned key off. Any ideas?

When it shuts down and won't start for 15-30 mins, you need to find out what the engine is not getting. Check the fuel pressure and spark.

I believe is spark, it shuts off like you turned key off, fuel pump is still wotking as can hear it when key is turned on and stops when pressure is attained, then can turn key but no sputters or anything
