Is it slow to crank and then fires over or is it just cranking away?
Slow to crank:
check all batt connections and make sure they are charged
check starter connections
if still slow to crank it's probably your starter contacts
Cranking ok then check your fuel supply make sure the air/fuel filters are clean..even though the LP is new it can go out.
there's a black rubber plug on top of the fuel tank take it off a poke a hole in it w/an ice pick and replace it...sometimes there can be a lot of vaccum in the tank which can cause fuel starvation if not vented.
other may chime in but that's about all I can think of now.
