ISUZU TRUCK BACKFIRE PROBLEM

1991 Isuzu Truck • 140,000 miles

Trucks stalls and normal speeds, I can feel it begin to lose power. I coast to a stop. Sometime it starts right up. Somestimes it takes a few minutes. It is becoming more frequent, doing it every other day now. Changed fuel filter, didn't seem to help. Doesn't idle rough, doesn't backfire, just quietly loses power. Last time it would not start ntil the next day, maybe I flooded it, in an attempt to start it.

Have the fuel pressure tested. The fuel pump could be failing.
