1995 Dodge Dakota 5.2l V8 Magnum. The truck will stall shortly after ignition (sometimes right away, sometimes 15 min.). It's very rarely a stumbling stall, usually just an altogether cut-off. After the stall (about 90% of the time) the engine will not fire. It just turns and turns, but after sitting for a few hours The truck will start right up (and stall again if course)(flooding?). The rotor and cap has been replaced, the fuel injectors have been tested and cleaned, the coil has been replaced, the MAP sensor has tested good, the fuel pump is working fine (and the fuel rail never loses pressure), the crankshaft position sensor has been replaced, the IAC sensor has been replaced, the air charge temperature sensor was cleaned, and there is no sign of any vacuum leaks. Could the throttle position sensor cause this issue? Any other thoughts? Thanks!

As when an ignition module cuts off, then after cooling off, works again.
As when a faulty alarm relay cuts the engine out intermittently.
Many new parts in there now, is the distributor pickup coil new too?
Many more parts can be replaced at random without diagnosing. To save time and energy, diagnose. When it is having a tantrum it is time to check, motor needs fuel, spark, and compression to run and by what is happening, one needs to find which is absent, which keeps the motor from running.
Does it have spark, injector signal? A 12V led test light or a noid light is used to detect the quick electric signal.
My opinion is it's electric issue, ignition component failing (pickup coil, control module), alarm, and/or possibly the ignition switch.
