Was running fine when we bought it next couple days it started dying and wouldn't start back so replaced main relay and ran fine for couple hours the started same thing getting good fire from coil it really started after it gets warm
Any ideas

 

Maybe a fuel pump issue. Do you hear the pump turning on when turning the key to on position?

Have you verified ignition timing with a light?

 

Ditto the above^^^ replace the fuel pump, but first replace the ECTS, [Engine Coolant Temperature Sensor] assuming you mean engine temp. 94

 

Well guys the spark plug cylinders were full of oil replaced seals gasket and plugs seems to be doing fine now we will see in a few miles

 

You could always hear the fuel pump running
