Please help any info would be great

it is the alternator or the regulator. get parts store to swap out under warranty.

Do you have normal compression, fuel pressure, and spark ?

Make sure the trans cooler is getting a good air flow. and a trans flush is always good, and most oil change shops do it for around $89+

Is the check engine light on ? How does it run now that it has cooled off ?

The temp overheat could have been a false readiing due to a leak or low coolant level in the degas bottle(coolant expansion tank). The overheat signal is what induced the reduced power setting from the computer. Have your degas bottle checked at a dealership or by a competent mechcanic.

replace the alternator,this is the problem,please rate thank you.

this is a hard one to fiqure out unless the vehicle does not starty at all because you have distinguish if it is gas or spark. The distributer has a module that may be breaking down. You have to remove the Dist cap and rotor to get to the module. It has two screws that hold in place using 1/4 inch nut driver to remove it. You can take it to oriellys and they can test it to see if it is good or bad. If you have a check engine light on you can take the truck to auto zone to see what codes are in the system. They will do this for no charge.

i would start in fuse and relay area with voltmeter.

Did anyone check the clutch interlock switch? It's possible the position is out of adjustment. My 2008 SRT4 is right at the bottom. If you don't push the clutch ALL the way down, it won't start.

I had this happen to me before. My battery had went out and I had put another in (didn't buy a new one-- it was holiday). It did this exact thing to me. The scary part is once, it was on the interstate going about 75 mph... didn't die but all gauges went to nothing. It turned out that the battery I was using didn't have enough cold cranking amps and was pulling down the alternator too much so the computer shut it down. The one time it didn't... it was because the RPH's were too high. Try checking the battery and alternator... make sure you have the right battery and have an alternator shop test your alternator if the battery is good.
