I have 96 dodge ram 3500 dually with v10, truck sometimes has oroblemsvstarting, other times not. When I drive it, it will run fine, then it will start to loose power choke out and eventually die. If I let it cool down for 5-10 mins I can fire it back up and continue..until the next few miles. I had someone tow me, put tranny in neutral...and had it running during tow...the rpms would spike irradically as if I was stomping on accelerator. No check engine ligh, plugged snap on scanner in, no codes stored.. pressure seems to read steady ? Help symptoms are so irradict and odd for how it's running I have no idea where to even begin ...
