Now, I am not saying it will be the same for you as mine was an efi motor, not carbed, so not sure if that will be playing into it or not. I am no mechanic, but your symptoms are identical to what I had experienced.
I want to THANK YOU .Bigfishhunter . Thank you Thank you
Initially for the response , but THAT Was the FIX .The Voltage regulator rectifier. Replaced it last nite & tried this morning .

If it starts acting up again, check your oil level. I had the exact same syptoms. Ended up that my motor was burning oil, and I was out of oil. Blew up the motor. Mechanic couldn't even figure out that one. He thought it was a leak in some air hose that was causing the engine to flood or something. Wasn't happy with that diagnosis when the motor blew up.
