Air pressure builds one day then not the next.

I have a old oshkosh truck and within the last couple weeks upon starting first thing sometimes it will build air pressure and sometimes it won't.
On the times it won't if I go out and rev up the engine by hand it will start to build then be fine.
Not sure where to start checking, was told maybe check valves need to be replaced??
Any ideas would be appreaciated.
Thank you.
Kurt
