Usually it starts fine, and runs approx. 15-20 min., then starts missing and chugging when accelerating. If I slowly apply gas pedal it seems to catch then does accelerate. A little longer and it sputters, lurches. Then it doesn’t want to start. If I wait approx. 30 min. it starts again and go’s through same process.

  1. Ignition Control Module needs to be replaced.(most common)

    Slight chance the fuel pump is going out. Next time it doesn’t want to start, you can try spraying some starting fluid in the air filter or attach a fuel pressure gauge and see if you have a loss of fuel pressure.
