Initially noticed while running. Motor would lose power for a split second and come right back... Took it in to my shop. could nopt replicate on hose. Hooked to diagnostics. Also happens at startup. Engine loses communication with program. Checked ECU, Harness, and both main and starter relays, with known parts. all AOK. Problem persists. I tighten grounds, starts fine for 2-3 tries and then back to old problem. Any suggestions out there???
