B&S mower won't re-start after running

I have a mower with a B&S 5 hp engine that always starts immediately the first time (and runs great) but if stopped during cutting won't readly re-start until after a long rest (1 hr plus). Extra priming does not help. Occasionaly after about a dozen+ pulls it may re-start but usually not. Plug is good, filter clean and gas lines clear. This mower apparently has an auto speed/choke system as it has no manual choke/speed adjustments but does adjust to varying load conditions. When trying to re-start I sense the compression may be low but not sure at all.
Thanks for any advice

Check for spark when it won't start and see if there is still sufficient spark. You might just try a new plug to begin with.
