I see this often with a worn freewheel and most often, when under a heavy load (highly doubt bike has a cassette). Can be a variety of causes. New freewheel means you will want a new chain too at that time.
Positions on the Suntour shifter are related to indexing options as I recall. If so, shift lever is not original or your bike is newer (more likely), as Suntour indexing came out in 1987.
Cable and housing need replacement.
Here it is:
UL:- is for indexed shifting with an Ultra-7 (Narrow Spaced) Suntour Winner System 7-Speed freewheel.
P:- is for non-indexed power shifting with any freewheel, regardless of sprocket spacing.
RE:- is for indexed shifting with a standard spaced Suntour Winner System or a freewheel.
