So i replaced my FPR about two weeks ago on my 2002 f4i and my bike has been running fine since. Until yesterday, it shut off probly 6 or 7 times while riding it. The FI light would come on it would hesitate pretty bad at times. Any ideas?

 

Fuel pump, FPR, injector(s), wiring, relays, spark plugs, ignition coil, plug wires... could be anything really. First find out if the issue is that the bike is starving for fuel (pump, fpr, injectors not opening, faulty relay/wiring, etc) or getting too much fuel (fpr, injectors stuck open, plugs not firing, etc).
