Idle,yes! Accelerate no?

I have a 91' Heritage. The bike will idle, but when I try to accelerate I lose power and it starts to backfire and pop thru the carb. When I let off the gas it idles fine. I have noticed when this happens I lose some power to the system. I have cleaned the carb. Relaced the voltage regulator, ignition module and starter relay. Sometimes I will lose all power and it will not come back on for about 1 minute but then starts ok. Help!
 
Have you tried the simple things,like cleaning both ends of the battery cables?
You could be having intermittent contact.
 
Main breaker could be weak or the popping on accel could be a bad diaphragm in the top of the carb.
 
The main breaker was replaced 2 weeks ago. The battery was replaced 2 months ago and the terminals were cleaned. When I took apart the carb I cleaned the diaphram and looked for any holes or wear but did not see any. The thing that gets me is the loss of some system power? I will check the grounds again tomorrow, but it only happens when I accelerate.
