CUCV with HUMMV engine no hot start

[jdcucv]

I own a 1986 CUCV motor blew up replaced with HUMMV motor. Install and startup went good, but now once engine is warm or hot it will not restart. does anyone know why this is happening? thanks for the help.

i hate to say this, but you either have an issue with the glow plug temp sensor on the engine or the injector pump is rather worn and will be in need of a rebuild soon.
