HEAT?? problem 89 bronco

I have a 89 351efi bronco with a big problem but only when about 100 or higher outside air temp. after about an hour power drops then dies (acting like running out of gas) in about 30 min will start back up for about an hour again.. don't have a gas pressure gauge but pusing the valve on the injector rack gas will spray around 10" or so high.

Follow the ignition diagnostic procedure in Haynes (usually Ch.5 Sec.5) and then get a fuel pressure gauge.

For faster responses (like in minutes instead of months), go to fullsizebronco.com . F-series are welcome, but search a few times before posting a question that has already been answered 100x.
