Question: 82 Motorhome on Chevy p30 chassis fuel problems

Have a motor home on an 1982 P-30 Chevy Chassis with a 454. Having what I believe to be fuel starvation problem. Engine runs well in driveway, will run at 1500 rpm for extended period w/o any issue. But when driving, usually up small grade, begins to sputter and dies! Have replaced aux electric fuel pump at tank, replaced all rubber fuel lines, replace filter at carb and inline filter. New coil, dist cap, rotor, and pick-up sensor under dist. Already checked for fire while driving, has fire as long as engine is turning over, so I feel it has to be a fuel issue. Any suggestions?

It sounds like the float may be sinking in in the carb. or the power circuit in the carb is plugged. Both would require a rebuild or replacement carb. but that is just a guess.

It's almost impossible to diagnose this type of problem long distance. You really need to have a mechanic to actually look at it and verify what is happening.
