Engine shuts down and won't restart for 1/2-3/4 hour. Here's the deal guys this engine will start and run perfect at the dock all day long take it out and run it for around 40 mins and it will shut off like you turned the key off leave it for around 45mins it will restart.
This is what has been done already, changed the PDP, all relay's have been changed the large blue capacitor is good, have even swapped the computer out just to try and the problem is still the same. ran the engine with the diag and the engine temp or EMM temp is not going beyond normal when the engine does it's thing, when it shuts down and you turn key off/on nothing happens fuel pump doesn't come on or engine doesn't crank and tachometer does it's system check then lights three lights on gauge and during this time at no time will the EMM communicate with the Diag software. At this point all points have been checked for proper voltage and all is well nothing out of the ordinary just wait the 40-45mins and she will run like normal again.
