This modle has a unexplained fuel pump fault. i wonder if its a factory defect. Cause as being a mehanic i came through alot of fuel pump problem and a fuel evaporator problems specially in the new tahoe although the yukon shares the same parts but a very few of them are defected. check the fuel pump pressure first, if its below the require range, replace it.

Vapor locking

What make , model an year vehicle ?Engine size too. Vapor lock is something that was associated with carburetors not fuel injection ! Do you have a check engine light lit on the dash ? How long must it sit before it starts ? Are the cooling fans working ? Sometimes they keep running after engine shuts off , depending on engine temp.

98 intreped stalls after getting warm, about 1/2 on temp. gauge. Then it will not restart fo 15 to 20 min. Also sometimes after driving and shutting down it will not restart untill after sitting for a...

98 and 99 intrepid was manufactured with weak fuel pumps causing them to vapor lock try pouring cool water on the fuel rails on the intake to calm vapored gas then try to start it. Even the temp gauge at half way mark is probably still low on coolant causing engine to be warmer than normal causing the vapor lock to fix this problem replace the fuel pump with a 2000 or newer intrepid fuel pump that carries a little higher psi to prevent vapor lock from reoccurring this pump is compatible with your 98 it will plug right in

2002 Chevy Impala wont start after letting sit after it warms up

Almost sound's like vapor lock , the fuel boils in the fuel injector rail , turns to vapor ! That was a common problem with carburetors , letting the vehicle hot soak after shutting down the vehicle an letting it sit for 10- 15 mins. The fuel would boil away ! Are the cooling fans working ? After turning off a hot engine the cooling fans can run on without the key being on , do you hear fans run ? What engine does your impala have ? 3.4 or 3.8 L . Has the check engine light come on ? The fuel pressure regulator could be leaking fuel . Pull the vacuum hose off the regulator after shut off the vehicle , is there fuel coming out of the regulator ? Dribbling out the end of the hose ? This could be bleeding the fuel from the fuel rail ! Good luck , hope i've given you something's to check that you haven't already .

P.1391 problem code car starts but run for 10 to 15 min then cuts out then when u try to start it back up it wont start or u have to keep foot on the gas machine is reading code p.1391

Well I have had this problem with these cars before. Every time I had one of these cars do this it always turned out to be the fuel pump. It would start perfect when it was the first time you started it for the day but when it was warm it would quit after awhile of driving it. Also it did seem to do it more if there was a 1/4 tank or less of gas. Also when i would drive them for a bit and shut it off and let it sit for about 15 mins and go out to restart it it would start super hard and run crappy till i got it going down the road. I think there is some seals in the fuel pump the go bad and start taking in a little air causing the car to get vapor locked. I just know when I had this problem I replaced the fuel pump and never had the problem again. Hope this helps. Don't forget to rate this. Thanks

My hummer has hard start when it's turned off for ashort period,

A scan tool should be able to read the temp pids at operating temperature to see if they are "off" enough to cause problems . Check for fuel lines to close to heat sources as boiling of the fuel causing vapor lock may be happening after heat soaking .

Suburban stalls while driving after running for 15-30 minutes. After letting it sit for 5-10 min it runs fine for another 5-10 minutes, then starts doing it all over again.

a bad crank sensor can cause this. shuts off while going down road, and will start about 10 min, later with no problems runs fine until it quits again. hope this helps,
