Ok people hope some one can point me in the right direction... my bus looses power after it warms up top end of gears higher rpm gust starts missing then when i slow down come to a stop wants to die. I've gone over all the distributor components points condenser rotor cap tuned up tuned again new plugs, tested coil... went over the vacuum system didn't see anything jump out at me??? does this sound familiar to anyone please help if you can gotta get them kids to day care and myself to work. i usually can find solution on my own but this time I have hit a wall.
Thanks for your time!

My next step would be a fuel pressure gauge on the test port with a long enough hose that I could put it where I could watch it as it craps out.

I drove from Nashville to Atlanta today and started missing/bucking coming down the mountain from Monteagle TN. At first the spit and sputter only on deceleration. Then got pretty aggressive on flats. Made it to a rest area and put in my new spare Temp II sensor and finished the drive without incident(another 2 hours) Hopefully tomorrow's 4 hours will be less eventful.
I would definitely check your Temp II sensor as well. That thing can cause some greif...
Good Luck!

Good call. You can check it easily if you have a multimeter and a temp gauge. It should fall on the pink line on this graph.
