Macerator pump issues

Help please! My 2013 Winnebago Vista 35F has 1-1/2 baths. The half bath has it's own black tank with a macerator pump to pump the waste to the dump. After opening the valves to dump and operating the pump I get barely a trickle of liquid and the pump shuts off after running about a minute. After a short time I can run the pump again with the same results. I'm assuming that the pump works but is overheating due to the lack of liquid flowing through it. I'm guessing I have a clog between the black tank and the pump. Any suggestions on clearing the clog that doesn't involve a really nasty mess on me and in the compartment where the pump is? Thanks in advance for your help!

FIRST, I fail to be able to determine if you are having an issue with the waste leaving the toilet(the macerator pump) or the fresh water entering the toilet to allow a proper flush. (a fresh water pump or toilet valve issue).
