OK just got the rebuilt pump on $1800
And it seems to work perfectly
I will put it to work tomorrow
Hear is what I learned if it happens again
Check fuel pressure
If low or negative
Pull fuel return line if you got good return flow
Stop and pull the injection pump it is more than likely bad

Stanadyne de10 rotary pump
Thanks for all the help everyone
