1985 Heriitage 2000 P30 workhorse chasis with chevy 454 engine; Headed out on a trip and 26 miles later it looses power and sputters and bucks and stops running. It would turn over and over but not start.:M Gas pumps are ok. Got towed home. The next day it started right up, drove it up our long driveway and it died halfway...No more start!:h I previously replaced the inline electric fuel pump, drained the gas tank, replaced the fuel lines, cleaned out the tank.
However unlikely, the final diagnosis after about 3 years of this intermittant problem was;:S The coil, located in the distributor was intermitant. Replaced it and it's been Happy Motorcoaching since then. :)
