Kohler 5CKM21 no compression in both cylinders

Finally got to go camping last week, started the genset to heat lunch, it started right up, ran for no more than 10 mins then died. Would not start again. Checked fuel pump plenty of fuel squirted out...

IF the cylinders built up compression with the spark plug feed, nothing coming out intake or exhause or crankcase vent or (if water cooled) radiator...

I"m stumped

You need 3 things to varroom
Fuel and air mixed in the proper portion (Explosive mix)
Compression (Appears you got that)
Spark. (Gasoline engines)
Heat (Diesel)
