06 ram 2500 5.7 hemi

Starts fine but after driving for a while I’ll turn the
truck off and it will loose all power and do like a
reset? Durning that time there is no power as in I
can’t roll the windows up or down or even lock it. If I
close the door fairly hard it will start working again.
Once I try to start again all the gay ages will reset
and it everything works fine untill I turn off. Some
times it does it and other times not. But more often
then not. Any ideas??
