i have a 95 k3500 6.5L when truck is warm going down road just shuts off put in neutral will start back up. when sitting in parking lot idling will shut off turn key will fire rite back up. any ideas will be helpful very strange no codes store in computer either.:confused:

Textbook PMD failure. Search the 6.5 forum for "PMD" and you'll find it's a common problem, easily fixed...but get it OUT of the engine compartment when you replace it and put a heatsink on the new one.

Fix it soon...once they start failing it will eventually totally quit and strand you.
