Stubborn Ram

[Dj Storm]

Ok the details:
2001 Ram 1500
Sport Off Road Package
Motor: 360
175k Miles


This past February I had to take the truck off the road for a while so it has sat almost 6 months. This past week I went out to work on it and it refused to fire. So I went and replaced the coil, plugs, plug wires, distributor, and rotor.

One touch on the key and it fired right up. I brought the RPMs up to let it blow out any crap and get things moving. After about five minutes it started chugging and died and would not restart.

I took the throttle body off, cleaned the IAT out, and cleaned the whole throttle body. Put it back together and once again it fired up...idled perfectly fine for about five minutes and died again and would not restart, it will just crank.

If I let it sit for a while...like an hour it will fire back up and proceed to do the same thing.

Any ideas or suggestions as to hat it could be or where I need to look next?

Thanks in advance for any advice.

Id put a scanner on it and watch it die. If you dont have access to one start by checking the easy things when it no longer runs. Like fuel pressure at the rail and spark at the plug

Here is a video I took really quick when it was running and just died. Maybe this will help a bit.

Is it always the same temp when it dies? I know you said you have to let it cool down before it will run. A loose conection that is fine cold but once the motor warms up enough pop goes the weasel...

I will make note of the temp when it dies the next few times and see if there is a constant temp.

You might want to have the battery check

OK now it gets stranger. Hooked a scanner up to the truck...Scanner will not even activate. Checked it on my Chevy and Chrysler...it works on them. Could the ECM/PCM be going bad by any chance? I had someone tell me that the engine has a "Start" and a "Run" mode. The computer doesn't start reading the sensors until it has been running a few minutes. I may try to hit a junk yard for a working computer and swap it out and see if it runs
