STARTING WHEN WARM

1998 Ford F-150 • 150,000 miles

My truck starts sometimes and then doesn't start at all when warm. Sprayed starting fluid in and then started and ran. Turned off checked fuel pressure with tester it restarted and ran at like 30lbs psi. Drove around for 1/2 hr, wouldn't restart, tried staring fluid, almost started but then wouldn't. Possible vapor lock, but not sure where to look, any suggestions. Thanks.

When it doesn't start pop the gas cap off an see if it starts?That will rule out a vapor lock. Also when it doesn't start you have good fuel pressure?
