it dies check the oil level in the high pressure pump resevoir,there is a small plug on top you can remove or you can just take out the oil pressure switch,the oil level should about an inch from the top.

The oil was about an inch but didn't remove oil pressure switch. It did get hot under the valve cover by the smell

Hot like electrical hot smell?

Yes, when it all started i was driving down the road and it died like starving for fuel. Or a electrical burn smell

have you checked the other valve cover? these early powerstrokes had a problem with the valve cover connectors getting hot and burning.

i will have him check the other one tommorw. could there be any other electrical problems that i need to get checked out?

Yes have them check the wires to the IPR(injection pressure regulator),I have seen them get oil soaked and then the wires will break after the insulation gets soft.

what about the high pressure oil pump?

The high pressure pump usually creates a no start or hard start hot condition,you could have them monitor ICP pressure when it is running and then stall to see if it drops below 400psi.
