Stealth Throttle

Dodge Stealth Not Running Right?
It runs fine when you first start it up but as soon as it gets warm at all it stalls or runs very rough, It will die or come close if you push the accelerator but idles fine. Any other ideas or imputs are greatly appreciated. Thank you. any questions you can also email me at adioskater56@gmail.com.
Recently Replaced:
Timing Belt
Mass Air Flow Sensor
O2 Sensor
Fuel Pump
Sending Unit
Fuel Filter
Air Filter
Fuel Pressure Regulator
Distributor Cap
Rotar
Plug Wires
Plugs
Battery
Terminals
I replaced all these parts hoping it was one of them.
My other idea:
Throttle Position Sensor
Sometimes when a car starts and runs OK and then warms up it looses power due to a faulty coil. check your coil output when hot, should be at least 40K
