Mid-flight I've had this issue come up several times now with my Avidyne Entegra MFD & PFD where the fuel flow information, fuel remaining, fuel used, and power percentages have gone out on my MFD (engine & maps page), and PFD (lower right box showing fuel flows and upper left showing power %). It has now happened 3 of the last 4 flights, at varying flight times from 15 minutes of flight to 2+ hours of flight before it went out on me.  

Has anyone else experienced this issue? 

I am thinking it could be a connector issue mainly as EGT/CHT information is all working just fine, and all other items are working fine with the PFD/MFD presently.

Sounds like a fuel flow transducer failure.  A small thumb-shaped box in the fuel line between the fuel pump and spider.  It has a spinning wheel inside that digitizes the amount of fuel being consumed by the engine.  Mine failed a while ago with similar symptoms.
