Once in a it dies or will not start, check engine light doesn't come on at all! on 1995 Dodge Ram 1500

What ever the problem is it affects the check engine light! When you turn the key you know if it's going to start or not if the check engine light comes on it'll start, if it doesn't it will not! The problem comes and goes with no warning, the first time it restarted in about an hour, the second time it was a week or so before I could start it!

No power to ecm or ecm is failing! Possible asd relay, or wiring to ecm.
Mechanic needs to have it when it will NOT start. Not much you can do!
Thank you! What is the asd relay? Also where is it locate?
