the car starts fine but once it gets hot enough under the hood the engine shuts off as soon as i touch the gas pedal. the engine will start again without problem but as soon as gas pedal is pressed engine shuts off. tests have been done to point fingers at the ignition but dont know which part of the ignition system is the problem. not fuel or tps problem. i have a HKS twin power. any input will be helpful. thanks guys.
