I have an 89 Force 150 that runs and puts out water through the 2 holes but after it runs for about 3-4 minutes it stops putting out water and shuts off. If I let it sit a while then try to restart it will run for a while and shut down again. Would this be the impellar or would it be the thermostat.

Sounds like the impeller.Do a compression /spark test to see if there is any damage to the head.
Every time you get it hot enough to shut it down your doing real damage to the cylinder/bearings/ rings/head gasket etc.
Change the impeller,before you do any more damage.Then if it does it again the thermostat will be the next thing to check.Make sure the vanes of the impeller are all there or accounted for.J.
