Loss in vacuum, what went wrong?

Okay guys, as you can see from the pics the mold would not allow me to use infusion mesh over the entire mold surface due to some of the complex shapes.
The resin started okay but when the laminate was around 1/3 way I started losing vacuum on the inlet side, the bag became loose and resin flow slowed. 
vacuum...as soon as the resin hit the laminate, everything behind the resin line (wet area) I lose vacuum, everything in front (dry) retains vacuum pressure.
Is this caused by vacuum not correctly distributed?

thanks guys! 
Just as i suspected, thanks for the clarification.

My laminates so far have always used the Soric XF, which allowed me not to use mesh across the entire part.

thanks again guys, ill give it another shot! waiting on my Easy Lease to arrive here in the Houston, since we don't have anything comparable. (using Fiberlease, similar but requires lots! of buffing to obtain the gloss)
Items like GC50 and Easy lease just cant be found in the states Sad, appears were behind on technology over here compared to you guys. and shipping is a killer on large quantities.
