WONT ACCELERATE WHEN HOT

2002 Nissan Frontier

Engine Performance problem
2002 Nissan Frontier 6 cyl Two Wheel Drive Automatic 111184 miles

my nissan is supercharged and it seems to lack horse power or tourque when it heats up an is getting very bad gas mil. About 216 miles per tank. It used to run very very strong now its hard to gett it going even enough to pass on the highway. The fuel pump seems to whine when the car starts. Im not getting any cdes and have done a tune up. Fuel volume? Fuel filter? I changed the filter once already not even 10000 mi ago. ? Can you help?
