Have a '96 Georgie Boy Cruise Master on a Chevy 454 P30 chassis. DH thinks we are having a problem with the fuel pump. I did a search but most of the topics are not specific enough for him! Anyway if...
Assuming a current tune up is in-place then it could well be a fuel pressure issue. Your engine probably is using a TBI system instead of the vortec mentioned. However, the problem may be the same. Check fuel pressure when running and then again after it has been shut off for a few hours... I suspect you may find the pressure has dropped considerably. Good luck, Gary
