Check for bad / or shorted crankshaft position sensor

Crank Position Sensor sounds right. If you let it sit for awhile it starts up again or its good for days then acts up.

The engine will crank , so starters good. Just noticed that I can not start the truck and all the instruments gauge are not working. But when i do get it started the gauges all work again. No warning lamps turn on. Kinda like turning off a light switch.

Sounds like ecm.

Actually it was the PCM. Had Dodge check it out. Thanks for all the help that was given. It has been running really good after a new one and re programmed. Thanks again for all the help here.
