2000 1500 dies

Ok, so i am new to dodge trucks. I have a 2000 1500 4x4 5.9 magnum. 200k+ mikes on truck 8pk on motor. A few days ago while i was driving it cut out on me while driving. Its like all gages stopped and the engine cut out for a split second. Then the next day it stopped on me at a light and it took a second to restart. Had to crank it that time. The last time it did it was while i was driving, again dash went out rpms stayed at 1000. Luckily I was near a street to turn down. Went about 100 feet and it started back up all by itself and just continued driving.

Considering it restarted and tach acts funny, I'd be considering crank sensor

Wouldn't i check CEL? Its weird, the tach will stay at the RPM that it was at when the engine cut out, and the Speedo and all other gauges drop as if i turned the key off. And the one time it did it at a light it almost acted like i was trying to start it in gear. and then all the sudden the dash lights came on as if the key was in the run position. Thinking maybe ignition switch. I do have a bad fuel pressure regulator so i cycle the key 4-5 times before i start to get pressure in the system. (have new one will replace this weekend).

Hit or miss whether the CEL is triggered. More often than not a crank sensor does not trigger it.
