check the alternator fuse that can be a fuse link by the battery pole,check alternator voltage on the alternator red wire or connector,it should the same as on the battery ,check ground wires for loose intermitent contact

Your problem may be in the connector where it plugs into the sending unit if the terminals are spread and not making good contact you will have voltage drop and cause the pump to overheat.
check with your car Quest dealer and see if they have a pig tail that you can solder onto your harness this will most likely solve your problem

try cleaning the inside of the MAF sensor and do the following procedure as well.
Here is the most common cause of surges and stalls at stops and low erratic idle speed and rough idle, it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
