Make sure the vent is open on the fuel tank, whether it is a built-in one or an external one. That's one step.

It's also very possible that the ignition system has a problem that acts up only after the engine is warm. That one probably has the solid state ignition, which is often a problem on those outboards. You can test this by running the engine until it quits working, then test the spark. Not easy, on the water, but it can be done.

Bottom line with those Eska-made Sears engines is that after 33 years, they're not especially a reliable power plant. Ignition parts are very, very hard to find. Other parts are available from www.certifiedpartscorp.com, but you have to call the place and talk to someone.

With the model number, you can go to www.searspartsdirect.com and see exploded-view parts diagrams, and Sears does have some parts available.

Good luck!

Check for spark.If your running a remote tank there is a fuel pump in the mounting flange of the carb that is a weak link. You might try squeezing the primer bulb to see it it helps.

REDFISH25, I would recommend a few things....a carb rebuild and pulling the powerhead off the leg to check the lower crankshaft seal for leaks. Both of these things can cause operating issues once the engine is warm. These engines are very simple, and not much can go wrong with them once you check the key areas (carb, lower crank seal, ignition). Some posters have mentioned that it's difficult to get ignition parts for these engines. That's not really a problem - if your ignition is bad, there is a company who rebuilds the ignition module under the flywheel, and even though the ignition coil is no longer available, it can be replaced with a Johnson/Evinrude ignition coil. I did this on mine, and it works great. These engines are very reliable, if you put a little effort into making sure they are set up right.
