Hi Greg,

Have you checked the fuel system? If the vent lines on the tank are
capped off, the tank will build up a vacuum and that could cause a
fuel pressure problem.

The other possibility is a wiring issue... Check the connections at
the ECU and the coil.  A bad coil can cause power loss under high
load conditions but still work fine at idle and lower speeds.


Happy Trails,
