My 96 dodge ram 1500 4x4 with a 5.2 ran great and then one day would start but die when put in gear. Problem persisted checked codes and a cam sensor code showed up. Replaced cam sensor, crank shaft sensor, new plugs and wires. Still same thing. checked fuel pressure and it read low, replaced fuel pump. still having problems, runs a little better but still backfires idles ok for 15 seconds then loses power, wont run stalls. HELP!!!!
This may sound weird but check your exhausts more so your cat. If it has clogged up it will make the truck do some weired things.
Kind of sounds to me like you have an o2 sensor problem.

I WOULD SAY IT IS THE COMPUTER {BRAIN} THAT IS WHAT SENDS THE FIREING ORDER AND VOLTAGE AND SETS THE TIMEING SPECK I WOULD SAY CHECK THE COMP

There are to many things that can cause the no start. Here is a link that can help you understand the possible problems and links to how to retrieve the DTC codes which is activating your Auto Shutdown relay.
Good luck and hope this helps. Keep me posted

Find your firewall electrical junction block (where all the wires enter the cabin on the passenger side) and with a zip tie pull up the wire bundle so it does not ride on the upper tie rods and, fasten the zip tie to anything that is solid in the engine compartment and, let me know what happens
